Hello Anish,
I would like to get the full error message no., by the meantime, this kind of error message is issued when checking an entered tax jurisdiction code against the in SAP defined tax jurisdiction codes in table TTXJ and the entered tax jurisdiction code does not exist.
Please make sure the object DNL_CUST_TXCD is downloaded to our CRM system as this usually causes the problem as well. please review note 507741.
thanks
Willie
