List of DDIC structures with erroneous Enhancement Category
In this blog post, I propose a little program to detect all DDIC structures and tables with invalid Enhancement Categories. It’s largely inspired by the SAP program Z_CHECK_ENH_CAT provided in the note 2205573 – Checking enhancement category for data dictionary objects with SAP tool, but this SAP program is to analyze just one given DDIC structure or table at a time.
The reason why I created this program was that after adding few more possible values to a custom DDIC domain and activating it, the activation log reported few standard DDIC structures with syntax errors, especially the DDIC structure PSHLP_CUSTFLDS_NTWK_ST. A check on it:
DDIC Structure check error
A fix is proposed by the note 1834868 – PSHLP: Syntax error in Customer field structures of HLP which consists in adjusting the Enhancement Category via SE11 > menu option Extras > Enhancement Category.
This syntax error didn’t seem to be a problem in production, but maybe this structure was actually never used. I created a little test program to use that DDIC structure, the program could activate, only a warning was reported by the Extended Check (SLIN).
I don’t know why it wasn’t detected earlier, so maybe we had other DDIC tables and structures in the same situation. It’s why I decided to extend the SAP program to detect all of them.
Selection screen of Z_CHECK_ENH_CAT_ALL
The result shows all analyzed DDIC tables and structures.
Just search “FAIL” to directly go to the errors.
Result of Z_CHECK_ENH_CAT_ALL
In the example above, you can see that the Enhancement Category of ZBAPI_TE_DPR_PHASE is inconsistent. It’s because it includes BAPI_TE_DPR_PHASE whose Category is Can be Enhanced (without restriction), so ZBAPI_TE_DPR_PHASE Category should also be Can be Enhanced (at the time of the run it was Extensible alpha and numeric).
I hope this will help.

This is a program from an SAP note you have adapted as I understand it?
That is, SAP are - in 2022 - 22 years after ABAP Objects - providing programs with FORM routines as modularization units, and this is not even a procedural program as the bulk if the logic is in a big blob after START-Of-SELECTION.
We all have to write quick and dirty quick fix programs but I just cannot bear to have all the code after START-OF-SELECTION. At the very minimum I have the quick and dirty code in a FORM routine.
I am also bursting to know what the ASSERT 1 = 1 thing is all about.
And while I am here ... in some systems at work when I create a new structure or table the enhancement category defaults to "cannot be modified" which is good as a default. In some systems it does not, same as historically and when you activate the structure/table you get the "enhancement category not defined" warning. What is controlling that? Our German system has a higher support stack level than our AUS system and yet the AUS system gets the "good" behaviour and the DE system gets the "bad" behaviour.
Yes, the subroutines of the check part comes from the SAP program Z_CHECK_ENH_CAT provided in the note 2205573 – Checking enhancement category for data dictionary objects with SAP tool. I just added a part to repeat the check for each structure and table that contains DDIC objects (tables, structures, data elements, domains) of given packages.
It's a quick and dirty program, "one-time" usage. Just copy/paste in your system if you need to scan your system, and delete it after usage. Better sharing it than keeping it just for me, it could help. I moved the code into a form and I removed ASSERT 1 = 1 (I use it to just add a breakpoint at parts where the debugger can't go, like end of event, end of implicit enhancement, and so on).
No idea about the default enhancement category.
