How To Fix AP257 - Modification de l'affectation impossible

SAP Error Message - Details

• Message type: E = Error

• Message class: AP - Investment program messages

• Message number: 257

• Message text: Modification de l'affectation impossible

Quelle est la cause de ce problème?

You want to change the assignment of a measure (or of an appropriation
request) to a program position. However, the program position specifies
that the measure (or the measures assigned to the appropriation
request) receives its budget by means of budget distribution from this
program position, and a budget has already been distributed to the
measure (to the measures assigned to the appropriation request). It is
therefore no longer possible to change the assignment.

Réponse du système

Changing the assignment is not allowed.

Comment corriger cette erreur?

First return the budget from the measure (from the measures that are
subordinate to the appropriation request) to the program position.

Le système émet un message d'erreur et ne vous permettra pas de poursuivre cette transaction tant que l'erreur n'est pas résolue.
