The SAP error message CNV_PE246: Receiver cannot be included, transfer list already has data typically occurs during data transfer processes, particularly in the context of SAP data migration or conversion projects. This error indicates that the system is trying to add a new receiver (such as a target system or data object) to a transfer list that already contains data.
