  • If you follow me on social media, you probably already know that I have written a book about ABAP in Eclipse. The full title is: ABAP in Eclipse – Install, Configure, Use, and Enhance Your ADT and it is pointed to all ADT users as it covers the topics from installation up to extension of Eclipse. If you have the book, let me know your feedback, as this is most important for an author to see where he did well and where he need to still learn.      Cheers 
  • Column ID is not really a special field in ALV. It is always filled automatically by ALV and your manual entries are overwritten and set to the same value as COL_POS (Column position). I’ve prepared a demo program (ZDEMO_AIN_CL46) to show you, how the COL_ID is changing on a base of COL_POS. On the selection screen you can find two radio-buttons.   Figure 120 ZDEMO_AIN_CL46 Selection screen   When you select the first option – “COL_ID filled”,  the FCAT will be created with manual COL_ID.  
  • I was trying to find an usage of this field in ALV, but I failed. Any of known behaviours of ALV didn’t shown anything on a base of this field.  
  • Hotspot fields are very widely used in ALV, such fields have the behaviour and style of hyperlinks, which means they are triggering the single-click event of ALV called HOTSPOT_CLICK. It is commonly used to show the details of the clicked object, or to move to a transaction in which the object can be modified. As you can imagine, setting column as a HOTSPOT is very easy, you need to pass only the ABAP_TRUE (‘X’) value to the field catalog, but this will only change the style of the field (content of the field is underlined) and it will fire the […]
  • Group key is not widely used but it has nice feature. Once you group the field catalog fields and you pass the group name into parameter IT_SPECIAL_GROUPS of method SET_TABLE_FOR_FIRST_DISPLAY, then in selection of fields to display in layout change window, you’ll be able to choose to see all hidden fields or the hidden fields from the group you’ve created. If you don’t pass the group name into IT_SPECIAL_GROUPS, then this setting of field catalog has no impact on display.   For my demo program ZDEMO_AIN_CL43, I’ve created a field catalog with REF_TABLE filled for all fields, so it is […]
  • You may suspect that setting up a domain name in the field catalog will make some effect on the display, for example in data type, length, lowercase sign,  but it seems that it has no effect in ALV grid. Maybe just for information and for Report-Report interface, where this field is use as one of the matching criteria for selection-screen parameters. As you can see on the next image, although I gave the DOMNAME value FLAG, it didn’t changed anything in the field catalog.   Figure 108 DOMNAME in Field catalog https://gist-it.appspot.com/https://github.com/fidley/ALVGridInNutshell/blob/master/src/fcat/zdemo_ain_cl42.prog.abap?footer=minimal
  • Before writing this part, I was never using Report-Report Interface, so probably it is not common scenario to do so, or it is not used with the systems I had possibility to use. But anyway I’ve made a deep dive into topic, to understand how we can use this interface and for which purpose.   Seems that, using this interface, you can call from ALV grid an BW Query, SAP Query, ABAP Report Program or Transaction. Probably depending on the installed version of your system, or addons, the list of the interfaces may be longer. Anyway I’ve focused here on […]
  • This field allows us to set (or change) the header text of the column. It can consist up to 55 characters in lowercase mode. When you use data dictionary reference ( REF_FIELD, REF_TABLE ) it is populated automatically from the data element of the referenced field. Figure 97 Texts of Data Element S_FROMAIRP  
  • The changes of this parameter are only visible in edit mode and makes sense only for character or string fields. If it is set to ABAP_TRUE (‘X’), then the ALV grid stores in internal table the value in lowercase, if the value of the parameter is empty, then it will always convert the entered value to uppercase.   Figure 96 Results of zdemo_ain_cl39 with lowercase turned on     https://gist-it.appspot.com/https://github.com/fidley/ALVGridInNutshell/blob/master/src/fcat/zdemo_ain_cl39.prog.abap?footer=minimal
  • As the description says, the meaning of that field is to set the internal length of the field in Bytes. During my whole career as ABAP Developer, I had never filled that field manually. Usually you’ll not bother yourself about it. But if you do, then take into consideration following information: Length is in Bytes, so remember that it doesn’t mean, that one character takes one Byte In display mode, you’ll not notice probably any change When you’ll setup this incorrectly, you may have problems when you allow grid to be editable, for example: When I’ve set the INTLEN to […]
  • One of the standard requests that comes with every SAP implementation is automatic download of exchange rates to your system. Today I will show you on an example of Central Bank Of Turkey, how to transform XML from bank site into internal table, which can be then used inside your code to populate values of  BAPI_EXCHANGERATE_CREATE FM. There are few ways to download the XML to your ABAP code, I prefer to create an RFC destination (lets call it here Z_DESTINATION_TO_TCMB), as on many servers you need to provide credentials for PROXY and it is safer to keep it saved inside […]
  • Following the example of downloading exchange rates from Central Bank Of Turkey using transformations, please find bellow the same way for National Bank of Poland. Again, lets create an RFC destination (lets call it here Z_DESTINATION_TO_NBP) tha will point to https://www.nbp.pl/kursy/xml/lasta.xml, where the last exchange rates are posted.
  • Yesterday I've announced that I'm working on automatic logon to SAP systems on Eclipse. Today the changes in the plugin ABAP Extensions for Eclipse are published and you can use the first version of the automatic logon on your installations.   ABAP Extensions plugin you can find in Eclipse Marketplace or by doing direct installation from this link http://abapblog.com/eclipse/plugin/ABAPFavorites/ or by using the install button which you can find on the right side of this page.   After installation of update will be able to set the preference if you want to do automatic logon at start of Eclipse and if you […]
  • As you can imagine, INTTYPE is just a presentation of DATATYPE in internal SAP format in most of cases. I wrote most of cases because it can also say if the field in internal table is a reference to other type, or for example a table. Just like DATATYPE, you don’t need to fill this field manually, when you’ll leave it empty, ALV grid will automatically setup a proper type according to referenced internal table field. But if you’ll have unstoppable need of filling it, then the behaviour of the column will be exactly the same like you would use […]
  • DATATYPE field has small influence on the way the column is displayed. You can omit this field and then ALV grid will automatically fill this field and additionally JUST, OUTPUTLEN, INTTYPE, INTLEN and DD_OUTLEN on a base of the type of the output table field.   But if you decide to fill it, then on a base of DATATYPE you’ll notice different justification or output length. But still all checks of the data entered in edit mode will be done on a base of the real data type of the linked internal table field. Possible data types form system NW […]
  • The main functionality of the ROLLNAME is to provide a data element that will be responsible for showing F1 help on the grid cell. If in data element the documentation is available, then it will be shown. If not, or if the ROLLNAME will be empty, you’ll receive the message “No documentation available” when you’ll press F1 on a grid cell. Figure 84 Result of F1 with empty ROLLNAME   In the demo program I’ve used data element S_CONN_ID to show you how does it work. Figure 85 ZDEMO_AIN_CL35 Selection Screen   On the first sight you can notice that […]
  • TOOLTIP, as in any other places in on your PC, is responsible to show short info about the column when you hover your mouse over the column header. It’s very useful when you have a lots of fields in you grid and you’re optimizing the width of the column by minimizing the description of the column itself. It is common behaviour for example for checkboxes or for icon columns. In this case the Tooltip is very helpful for explaining the user the meaning of the column. Figure 81 ZDEMO_AIN_CL34 Tooltip of an column     Additionally if you’ll not use […]
  •   SELTEXT is one of the fields that are linked to the texts of the grid columns. This particular one is responsible for displaying the name of the column in the change/display of layout popup. Figure 79 ZDEMO_AIN_CL33 Column description in the layout popup   In case the TOOLTIP field is empty, the value from SELTEXT will be also used as tooltip and will appear when you hover the mouse over the column in the grid.    Figure 80 ZDEMO_AIN_CL33 SELTEXT as a TOOLTIP   https://gist-it.appspot.com/https://github.com/fidley/ALVGridInNutshell/blob/master/src/fcat/zdemo_ain_cl33.prog.abap?footer=minimal  
  • Conversion Exit was already mentioned while describing the EDIT_MASK field, but here it is called in a bit different way. Before saying how, it is important to understand the conversion exits. They are no more and no less than a function modules that helps to represent the internal values into understandable or more readable values. An basic example is field MATNR which is 18 characters long in ECC and 40 in S/4 HANA, and if it contains only numbers (for example 123),  then the internal value is stored with leading zeros, for example 000000000000000123 in ECC system. As you can […]
  • Technical field allows you to do similar thing as NO_OUT, you can hide the field on the output, the difference is that, users are not able to unhide this field. As NO_OUT, in order that TECH field work, you need to set its value to ‘X’.   Figure 70 ZDEMO_AIN_CL30 Setting of Field as Technical   Such setting is very helpful when you have to store some additional values in the internal table that supposed to be displayed, but you do not want to display them. Such field can be used for example during the event handling or displaying totals […]

  • Are Comments overrated? Comments are a wonderful tool to document what you intended with certain program logic. You can place it directly where that logic resides: In the source code. As comments are non-functional, they are not getting compiled and hence, not executed. However, I’ve got the feeling that sometimes we should really think about […]
  • What help.sap.com doesn’t tell us I thought, SAP is pretty clear in what they tell us about the _SCOPE-parameter that can be passed to every enqueue-function modul.

  • Subscribe to my Video UpdatesRequest a Free ConsultationHow do slowdowns affect the hiring process for authorities and job-seekers in the marketplace?As someone who owns an executive search firm, I’m very in tune with the employment market. A slowdown will actually help hiring authorities be better able to find talented candidates. For the last two or three years, I know it’s been tough to find talented people. This also means that job-seekers will better be able to find work. Mind you, no one is rooting for a full-on recession, but a little economic slowdown won’t necessarily be a bad thing […]
  • The Houston Astros are not only my favorite baseball team, but they’re also great teachers of business. Here’s what I mean.Subscribe to my Video UpdatesRequest a Free ConsultationI’m a big Astros fan, but their recent World Series title isn’t the only thing they’ve given me to smile about. They’ve also taught me a lot about business, and I think there are three things that all hiring authorities can learn from the Houston Astros:1. Rebuilding. The Astros literally went from worst to first in less than five years. How did they do it? They recognized the need for a rebuild […]

  • Subscribe to my Video UpdatesRequest a Free ConsultationLast time in part one of this series, we discussed strategies for boosting employee retention. Today in part two, we’ll focus on another important aspect of being an employer: employee engagement.Since 2010, numerous studies have come out that have really enlightened us as to what constitutes employee engagement, how it impacts productivity, and how it impacts employee retention. These studies have suggested that up to 80% of people don’t like their jobs and that dissatisfaction influences their disengagement.But what do those employees look like? Well, those are the people that might distract […]
  • Here are a few things you can do, tactically speaking, to bring about greater retention in your organization:First, conduct performance reviews and convey what your employees are doing well and the areas where they can improve. Rather than seeing it through the company lens, make the review about the employee, and gain a richer understanding of where they’d like to be in both the short term and long term.  Seek to understand what skills and experience they’ve developed that make them feel their job is worthwhile, as well as those that they’d like to fine-tune and develop further, so […]
  • A lot of things can impact your employer brand. One thing is just being aware of it.How you treat your existing employees has a major impact on your employer brand. People talk, and a lot of them find out about companies through word of mouth. When people leave or quit, how professional are your exit interviews? Do you learn about why they are leaving and try to change for the better? Doing so will improve your employer brand immensely.Another factor to consider is how you treat people through the interview process. Asking good questions, giving them fair offers, and […]
  • 2. Understand what motivates them besides money. Ask open-ended questions that inquire as to what they’re really looking for in their next opportunity. Are they looking to learn new skills? Are they career-motivated or quality-of-life motivated? How does your opportunity apply to their motivations?3. Don’t make offers without knowing they want to join your organization. 4. Stop lowballing people. Make a great offer on the first try, and only after they’re verbally pre-closed to accept. The only surprises in an offer should be if it’s more than the candidate expects.If you’d like to talk more about this topic, have any […]
