I have a Belgian company code for which all required configuration has been done. Now, when business wants to generate VAT returns, we suggested the following:
Step 1: Run S_ALR_87012357 (RFUMSV00)
Step 2: Run FOTV (FOT_B2A_ADMIN)
The mapping of tax codes to tax groups has been done in OBCG/ OBCH. However, if I compare the output from S_ALR_87012357 and FOTV output, the amounts are not matching as per the assignment of tax codes and tax groups.
Please advise if there is any way to find out how system is calculating amounts showing up in FOTV. Any pointers are most welcome.
