avoid IDOC creation via mass maintenance for replication (integration C4 <-> ERP)

Dear all,

there are customers in the ERP system which are marked for deletion. When using XD99 for mass data changes Idocs for such customers were created which is a not wished. With which mass maintenance tool like LSMW or MASS in ERP such behaviour can be avoided? Generally no Idocs for marked for deletion customers should be created at all. Is it relevant where in the customer master the marked for deletion check marks are set?

Kind Regards

Tanja
