Deletion Report for Reconciled (Duplicated)
SAP BP (RFTBUD03) 
This report program deletes the migrated (newly generated) SAP Business Partners. The SAP Business Partners that were present before the conversion remain the same, as you may already have concluded transactions with these business partners.
Technically, the report deletes all the records of the SAP Business Partner for this partner number. The actual record in the reconciliation table remains the same.

In the Treasury Business Partner table BP000, the PARTNER field has been included as a reference to the SAP Business Partner. When the conversion takes place, the partner number of the corresponding SAP Business Partner is stored in this field. The deletion report RFTBUD03 takes this into account, and enters the new reference here.
