Updating Contact person details
I need to update the details of a Contact person for a Customer in the tables KNVK and KNA1. I am using the standard FM ADDR_BUILD_PERSON_COMPLETE. The parameters I am passing here are ADDRNUMBER AND PERSNUMBER. I have written the entire code for it and there are no errors. But the Contact person details are not getting updated. I am not able to find what the problem is.
Pointers would be helpful.
