[ABAP] REDUCE as an alternative to line_exists for the use of other comparison operators such as >, <, >=, <=, CS, CN

By using line_exists you can check if a line exists or not exists, but it is not possible to use other comparison operators. A workaround can be REDUCE in that case.

In the following snippet, we want to check if there is a flight that costs more than $1000,

SELECT * FROM sflight INTO TABLE @DATA(flights).

* Check if flight with price > 1000 exist
IF REDUCE abap_bool( INIT price_gt_1000 = abap_false
                     FOR  line IN flights WHERE ( price > 1000 )
                     NEXT price_gt_1000 = abap_true ) EQ abap_true.
  " flight with price > 1000 exists

[ABAP] CATS – Difference between two times (CATSHOURS)

I had to calculate the difference between two times, even if the end time goes beyond the 0 o’clock day limit, e.g. 20:00 to 02:00 should be 6h. I found the following two function modules doing the job:

* Option 1
CALL FUNCTION 'CATS_COMPUTE_HOURS'
  EXPORTING
    pernr                    = pernr
    date                     = date
*   NO_BREAK_DEDUCTION       = ' '
    row                      = row
  TABLES
    return                   = return
  CHANGING
    catshours                = catshours
    beguz                    = beguz
    enduz                    = enduz
    vtken                    = vtken.

* Option 2 (I think it's only available on S/4 HANA)
CALL FUNCTION 'CATS_DETERMINE_HOURS'
  CHANGING
    catshours                = catshours
    beguz                    = beguz
    enduz                    = enduz.

[ABAP] Import Transport from ZIP

Report to import a ZIP file, containing the cofiles and data parts of a transport request. Related reports:
https://nocin.eu/abap-download-transport-as-zip/
https://nocin.eu/abap-create-toc-for-a-given-transport-release-it-and-download-it-as-zip/

This report can be handy, especially since S/4HANA 2023 seems to have restricted the “classic” import way by using TCode CG3Y and CG3Z. See note 1949906, where it is recommended to create a custom report.

[ABAP] Validate JSON data

[ABAP] Generate a QR-Code

There are many blogs describing how to create a QR-Code in the context of SAPscript or Smartforms (e.g. here, here, here and here). But I was looking for a way to generate a QR-Code and only receive the graphical data stream from it, without the need for any manual steps such a creation via SE73. During my search, I found these two notes, which contained all the information I needed:

  • 2790500: mentions the class CL_RSTX_BARCODE_RENDERER with method QR_CODE
  • 2030263: describes the parameters for a QC-Code creation
