Can't get variable from structure CI_CSKS after activating Exit COOMKS01

[Alexsander_Hoffmann]

Hello dear ABAP experts,

I have a requirement to add an additional field in the Cost Center master data. I did this with User-Exit COOMKS01.

However, I can't use the value after the input. SAP only saves what is stored in structure CSKS_CI instead.

And I can't move what is stored in CI_CSKS to the CSKS_CI structure.

Can someone who already implemented exit COOMKS01 tell me how am I supposed to get this input value?

Thanks in advance
Alexsander

The DDIC structure CSKS_CI is to be used for your screen fields according to the COOMKS01 documentation. You should declare it like any other DDIC structure used for the screen fields, with TABLES:

TABLES csks_ci.

CSKS_CI is not filled or read by the standard program. It's just the documentation which tells to use it for your screen fields. Technically speaking, I looked at S/4HANA 2023 code, CSKS_CI is not used by the standard, so you might not use it if you wish.

You have to implement the function modules below.

1. EXIT_SAPLKMA1_001 is called during the PBO (before display of your screen), get the data from the parameter USER_CSKS_CI and store it in a global variable (screen field for instance).
2. EXIT_SAPLKMA1_002 is called during the PAI (after user input), get the global variable (screen field for instance), and transfer its value to the return parameter USER_CSKS_CI.

The include LXKM1F00 provides an example:

Hello Sandra

I actually used the following code in the includes

But still the value is not passed to the CSKS_CI structure  and therefore is not carried forward into the main program.

Do you know what I am doing wrong?

Thank you

You should not use CI_CSKS. You should use CSKS_CI. Answer edited.

If needed, debug the standard code after the PAI (LKMA1F39):

Hello Sandra. I was getting error "csks_ci-zwerks is not provided" when changing my dynpro but I chose to activate anyways and now it works. Thank you very much!
