Diagnosis
You want to reassign a subtree of the investment program.
However, budget has already been distributed from one or more positionsin the subtree to the investment measures assigned to them. When thisis the case, it is no longer possible to reassign the subtree (fortechnical reasons).

System Response
The reassignment is not permitted.

Procedure
As a basic rule, you should only carry out budget distribution once thefinal structure of the investment program has been established. It isalso especially important after a fiscal year change that you makechanges in the program structure first, and then distribute the budget.
If you want to reassign the subtree anyway, you first have toreturn all the budget amounts that were distributed to the positionsof the subtree, so that the distributed budget on each program positionis zero.
