The tax number for tax number category NL0 is already maintained

Hi GTS gurus,

In GTS business partner transfer monitoring (/SAPSLL/PARTNER_APPL) we get the above mentioned error message.

I already checked table TFKTAXNUMTYPE in feeder system as well as in GTS but it looks fine to me (no difference in settings).

Did anyone ever come across this error message and knows what to do?

I guess there is no general customizing issue but a master data issue with the business partner...I was not able to figure out yet which is the cause of this error message.

Thanks in advance!

Kind Regards

Gregor
