Which BAdI/user-exit triggers for tax code MWSKZ?

Question

​Hello,

A tax code MWSKZ is being modified while generation of the accounting document,

it is displayed fine in FB01, but after the generation of the accounting document, I leave to FB03 and I find that the value of tax code is modified (FB03).

Example : in FB01 i entered A0 as tax Code and i save, in FB03 i find it changed to AA

I checked :

1. AC_Document
2. ACC_Document
3. EXIT_SAPLV60A_001
4. EXIT_SAPLV60B_008
5. substitutions

is there any other BADi or User exIt that change the value of MWSKZ in BSEG table.

Answer 1

There are few places where you can check,

1. BADI_ACC_DOCUMENT, it can be implemented you can check it from se18.
2. User-exit ACBAPI01, SMOD or CMOD.
3. This one is a little tricker, I guess. It can be defined in Validation of accounting document - OB28, or other OKC7, OKC9 etc. It can be changed in Exit, probably.

Check also the tax code assignment in GL master record (FS00).
