Making the same Line Item both Editable and Formula Driven
I was wondering if there is a way to make the same LI editable and formula-driven at the same time.
Assume that I have a module with a dimension D and line item L. Now the Line Item L is a list formatted dropdown of list P.
P is a property of dimension D, which is defined for certain items of list D but not all (say defined for D1 and D2 but not for D3; D1, D2, D3 being list items of D).
I want a line item, which picks up the pre-defined property value from P wherever it is present basis a formula, but lets the user select from the dropdown where no property is defined. I want to do this in one LI only.
