Setting of Deletion Indicator for Product Cost Collector

Hi Gurus, could you please help me with this question:

We need to turn off the repetitive mfg

indicator active for a group of materials. this in order to replace product collectors to production. While I was setting the deletion flag for the PCC I am getting the following error :

The deletion flag cannot be set for product cost collector 716402 for one or more of the following reasons:

There are still run schedule headers for the product cost collector in which the status Deletion indicator is not set.

There are production versions for the product cost collector in which the status Deletion indicator is not set.

There are postprocessing records in repetitive manufacturing that are to be assigned to the product cost collector.

There are manufacturing orders for the product cost collector in which the status Deletion indicator is not set.

System Response

The system does not set a deletion flag.

Would appreciate inputs....points will be awarded Liberally...

Cheers
