Diagnosis
The system was unable to carry out the forecast for an entire plant.This could be caused by existing locks on the forecast for the plant.In the case of parallel processing, it is also possible that newprocesses cannot be started for systematic reasons.

System Response
The system carries out no forecasts for any of the materials inthe plant.

Procedure

• There may also be messages available in the application log
(transaction WFCSL01) that give information about the causes of theproblem.

• Use transaction SM12 to check that are no deleted lock entries for the
lock object EMRP_RUN (subobject MDOBJ 'P'). The system would have beenunable to delete these locks if there were errors running the program(especially in parallel processing mode) during the forecast run.Delete the locks using transaction SM12 if necessary.
