Can't change Payment Card Information in Customer Master

[Former Member]

We are having issue with saving changes to customer credit cards:

Initial credit card info is saved on customer master. Any attempt to change existing card or add a new card to the same customer is not getting saved using transaction XD02. System does not give any error, it just does not save the information.

This behavior is only happening for customers for Account Group '0001 - Sold To Party'. It seems to me like we have done configuration for this account group but I have no idea what caused it.

Any help would be greatly appreciated.

Thanks!!

I wouldn't think the Account Group configuration would matter. This is related to storage of a card number in direct association with a Customer Number. What happens if you delete the existing card number and then try to add a new card number - will that update correct?

Also, are you using any form of encryption on the card numbers? Perhaps SAP's card number encryption or a third-party vendor's encryption?

Try setting breakpoints in the following function modules:

SD_CCARD_SAVE_DB

SD_CCARD_VCKUN_MAINTAIN

SD_CCARD_VCNUM_MAINTAIN

This should help you see if the INSERT commands are failing when trying to write the data to the VCKUN and VCNUM tables.
