Diagnosis
This may occur for a number of reasons. One possible cause is a parallelMRP planning run.

System Response
The ATP server is not updated.

Procedure
Check whether an MRP job is running simultaneously. This deactivates theATP server. Using modification note 704310, you can prevent the ATPserver from being deactivated. The ATP server is then updated by the MRPjob. However, the MRP job requires a longer runtime to do this.
If you start an MRP planning run in the dialog, the ATP server is notinvalidated, but updated.
If a parallel MRP job is not running, create a problem message undercomponent SD-BF-AC-TS. Mention both parameters of this message in thetext of the problem message. The first parameter refers to the table,the second parameter refers to the source code environment.
