 Persistency Indicator

Definition

Specifies what is to happen to a temporary quantity assignmentwhen saving or canceling an order.

Use

Temporary quantity assignments for pegging areas whose relevant location does not lie in the calling system can have different persistence. This is necessary as the temporary quantity assignments must persist beyond the Logical Unit of Work(LUW) in which they were created, due to the asynchronous nature of the ALE call.

In addition, temporary quantity assignments must retain their temporary character as long as the sales order from a second system has not yet been saved.

Structure

The persistence indicator can have the following values:

  • Nonpersistent

    Temporary quantity assignments have the persistence indicator Nonpersistent by default . These temporary quantity assignments are deleted when you save or cancel a sales order.

  • Prepersistent

    Temporary quantity assignments have persistence indicator Prepersistent if the following are true:

    • They belong to a system in which the ATP check was not triggered.

    • The LUW in which they were created is not closed.

  • Persistent

    Temporary quantity assignments are given persistence indicator persistent if you close the LUW with Save . The temporary quantity assignments are deleted if you close the LUW with Cancel .

  • Postpersistent

    If persistent temporary quantity assignments are read in another LUW or drawn for confirmation, they are given persistence indicator Postpersistent . If you close the LUW with Cancel , postpersistent temporary quantity assignments are given persistence indicator persistent again. This ensures that these temporary quantity assignments can be read in another LUW or drawn for confirmation. If they are given persistence indicator Nonpersistent , they are deleted irretrievably if a termination occurs.
