BADI or USER exIt for tax code - MWSKZ - BSEG table

[yassine_bouchama]

Hello,

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

it is displayed good in FB01, but, after the generation of the accounting document, i leave to FB03, i find that the vaue of tax code is modified (FB03).

Exemple : in FB01 i entred A0 as tax Code and i save,

in FB03 i find it changed to AA

i checked :

AC_Document, ACC_Document, EXIT_SAPLV60A_001, EXIT_SAPLV60B_008 and substitutions.

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

Best regards,

Yassine.
