We have got the below error in the log of Invoice Validation . We are on 11.5.10.0.2

Error ORA-20001: The tax cannot be calculated because the accounting code combination violates the defined security rules.

The full error is:

Validating invoice SJ/01013/11
The tax cannot be calculated because the accounting code combination violates the defined security rules.
Batch validation of the invoice failed
Error : ORA-20001: The tax cannot be calculated because the accounting code combination violates the defined security rules.

The main issue here is the Invoice Validation stops validating other invoices.

I greatly appreciate any suggestion and help!
