I wanted to add substition for business area for perticular G/L account in FI through OBBH tcode. Business rea is criticle filed & since business area field BSEG-GSBER was not in list of sustitution fields, I added it by unchecking the BEXCLUDE flag from table GB01. Then I created substitution as per requirements. But when I post the invoice from MIRO tcode,required business area is not seen accounting document created.
I created substitution for fileld BSEG-PARGB-Trading partner's business area, which was already given in list of fields for substitution. This substituion is working fine.
I tried substitution exit also.But no success.
Kindly povide me the solution.
