The document is marked as incorrect and subsequent processing can only
continue if an ATP check can be carried out successfully. The system
tries to re-establish the connection to the ATP System only if the
transaction is called up once again.

How to fix this error?

You must carry out the ATP check once again as soon as the connection to
the ATP System is re-established. To do this, mark the relevant items
and choose <LS>Availability Check</>.
The connection is also interrupted if a dump takes place in the (SAP)
