SAP Error Message - Details

• Message type: E = Error

• Message class: AG - Nachrichten ATP-Server

• Message number: 201

• Message text: The ATP server cannot be updated (table &1) (area &2)

What causes this issue?

This may occur for a number of reasons. One possible cause is a parallel
MRP planning run.

System Response

The ATP server is not updated.

How to fix this error?

Check whether an MRP job is running simultaneously. This deactivates the
ATP server. Using modification note 704310, you can prevent the ATP
server from being deactivated. The ATP server is then updated by the MRP
job. 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 not
invalidated, but updated.
If a parallel MRP job is not running, create a problem message under
component SD-BF-AC-TS. Mention both parameters of this message in the
text of the problem message. The first parameter refers to the table,
the second parameter refers to the source code environment.
