I have two multiline blocks , A and B. Typicall master and detai relation. B is the detail block from A.
I want to put a sum item in A block, getting the total ammount from her childs in the A block.
but i get the error: the item must be in the same block or the block must be only 1 record.
If i do the master block only 1 reg not problem, but i need this block multi reg too.
how can i put a sum item from detail block in the master block (multi line too)?
