Posted on by Community Power Pla... Microsoft Employee

I want to be able to edit the budget of a workpackage and if the sum of the budget for this specific workpackage is larger than the avaiable budget in the project table then the speficic budget for the workpackage should be set to the previous budget!

I have two tables Workpackage and Project

If(Sum(Filter(colA; Projektname = ThisItem.Projektname) ; Budget) + Value(ThisItem.Budget) - Value(LookUp(colA; ID = ThisItem.ID).Budget) <= Value(LookUp(Projektstammdaten; Projektname = ThisItem.Projektname).'Plan / Budget Faktura'); Select(Parent); ThisItem.Budget = LookUp(colA; ID = ThisItem.ID).Budget)

Hi @Anonymous ,

I have parsed this for ease of reference

If( Sum( Filter( colA; Projektname = ThisItem.Projektname ); Budget ) + Value(ThisItem.Budget) - Value( LookUp( colA; ID = ThisItem.ID ).Budget ) <= Value( LookUp( Projektstammdaten; Projektname = ThisItem.Projektname ).'Plan / Budget Faktura' ); Select(Parent); ThisItem.Budget = LookUp( colA; ID = ThisItem.ID ).Budget )

The fundamental issue if you are using this OnChange is that is is expecting an action - the first possibility is one

Select(Parent)

but this is not (an action) - it is simply a statement which really belongs in a filter (it does not set anything)

ThisItem.Budget = LookUp( colA; ID = ThisItem.ID ).Budget

I am not sure exactly what you are trying to do

@Anonymous ,

Yes, but this is not doing anything - it is simply a statement which you will get an error on as it is not an action.

ThisItem.Budget = LookUp( colA; ID = ThisItem.ID ).Budget

You need to specify the action required in the alternate circumstance (when you do not go to the gallery)

@Anonymous ,

Do you get any error on the posted code. If not, I need to understand what you two options are trying to do. One is Select(Parent) - where does that go and the other is reverting to previous budget. Bear in mind that I have no idea how or when you are writing data.
