I need to receive a message when different BP have the same Tax number, for Algeria - DZD. I activated the duplicate control for DZD in the transaction
The DZD exists in the V_TFKTAXNUMTYPE with function name: BUPA_TAX_NUMBER_CHECK.
The customizing seems to be ok. However, when I add the same Tax number in 2 different BPs, it is saved without any error or warning message. I have also tried with DZ0 and ZDZ (which is one we created, but the duplicate control also does not work)
Can you help?
Thank you & Kind regards,
