Summary :
When utilizing user exit EXIT_SAPLV01Z_002 in SAP, the function to propose an existing batch number triggers the exception BATCH_EXIST, due to a stringent existence check. To alleviate this restriction in certain business processes, this note advises implementation that enables the allowance of pre-existing batches by adjusting the function module's interface. Users must include the export parameter ALLOW_EXISTING_BATCH (type XFELD) to permit redefinition of existing batches. This adjustment is applicable in the context of module VB_CREATE_BATCH and is outlined for specific SAP versions including Release 4.6C with related corrections in Note 1119779.
