Need help in deleting values from (SAPMF02D)XKNVD in exit EXIT_SAPMF02D_001

Hi Experts,

I have to delete values from KNVD table in XD01 transaction based on a sales org. While creating a payer customer in exit EXIT_SAPMF02D_001 I can control this but don't know how to handle (SAPMF02D)XKNVD as this is having multiple entries. I have to delete few entries. I am able to handle one entry eg KNA1 records using field symbols but not multiple records in KNVD. Please suggest how to delete few entries from (SAPMF02D)XKNVD.

Thanks

Rahul
