Trying to assign (SAPLFACI)BKPF to a field-symbol

[walkerist79]

Hi, I have a custom program that has 2 IF ELSE conditions.

IF IDOC DOCUMENT IS POSTED.

ASSIGN ('(SAPLFACI)BKPF') TO FIELD-SYMBOL(<FS_BKPF>). <---This is the existing code and it works just fine.

ELSEIF IDOC DOCUMENT IS PARKED.

ASSIGN ('(SAPLFACI)BKPF') TO <FS_BKPF>. <---Tried to add this but it does not work. I'm not sure why. Is it because the IDOC is parked? But they both have accounting documents.

ENDIF.

The assignment trick allows access to global variables of all loaded code areas at runtime. The most likely answer is that Parked documents do not call any logic in the Function Group FACI and so that function group is not loaded at that code branch. You can test this by entering "(SAPLFACI)BKPF" in the debugger to see if that is an active reference for parked documents.

@juan_suros yes. that's what happening. Is there a way fo fetch (SAPLFACI)BKPF?

Not sure if this helps, but the segments of the idoc often have the reference document numbers. If your program doesn't have the idoc data you can look in table EDID4.

I've done this several times by just calling one of the function modules of the appropriate function group.

However, this has some possible drawbacks: This procedure requires a function module that can be called without any further impact on the current Idoc, so basically a dummy function module would be fine, e.g. one that gives back a value and does not modify any data.

Maybe the FM FI_ACC_GET would be worth looking at to do a dummy call and the function group is  properly initialized afterwards.

But still the question is, if you assign an external variable, you cannot expect that is has some meaningful value in the field symbol.

Because if you have to apply such tricks as above, the global variables in include SAPLFACI won't have any values either, just initial ones.

Okay. I was just trying to get the accounting number related that was generated by my IDOC since I need to use it for mapping values on CFDI. Currently, the data I have is just an IDOC number and I’m not sure where to start
