3764771 - BAdI SD_BIL_DATA_TRANSFER not triggered when saving Billing Document - SAP S/4HANA Cloud Public Edition

Custom Data Transfer BAdI SD_BIL_DATA_TRANSFER is not getting triggered when saving an existing Billing Document after changes in VF02, hence values from the Reference Document are not transferred to the Billing Document.

SAP S/4HANA Cloud Public Edition

Changes (VF02) to an existing Billing Document do not start the Data Transfer process from a Reference Document. Standard logic only runs the BAdI SD_BIL_DATA_TRANSFER during the creation of a new Billing Document when data is mapped from the Preceding Document.
