Diagnosis
When backflushing, the system determined that the current reportingreporting point structure does not correspond to the milestonestructure in the routing. This may occur if any milestone operationshave been added or deleted or if the control key of routing operationshas been changed. To update the reporting point structure, the systemtried to carry out a preliminary costing for cost collector &V1&. Thispreliminary costing failed. The backflush cannot be carried out.

Procedure
Carry out costing for product cost collector &V1& in dialog mode.Correct the error that prevented the creation of a new cost estimateand then carry out the costing for the product cost collector again.
Once the reporting point structure is up to date, the system can carryout the backflush.
