I am not able to edit 0 to 5% in unit cost %. Please guide what could be wrong here.
Screen shot attached.
You can only enter data if the dimensions (i.e. list) members are at the child level, i.e. not parent.
Pls ask yourself if the intersecting cell you're trying to enter data is at the child level.
Hint: Look at your subsidiary view too.
From your screenshot the line items contain different dimensionality to the module.
I suspect you updated the time frame from years to months for the module but not the individual line items.
