Transaction Nature (76/TN)
The system uses an algorithm to calculate the ICMS tax situation code. The algorithm uses the value in the Special Handling field in the Transaction Nature UDC table 76/TN. Therefore, you must set up special handling codes as follows:
00: Items that are exempt.
01: Items that have ICMS previously charged by tax substitution.
10: Items that are not taxed.
11: Items that are suspended.
Then, the system uses an algorithm to populate the Tax Situation field with a three-digit tax situation code.
