I'm trying to add a new UD column to a system Matrix which is already filled with data. Normally, on a form load, you can add a column to the matrix, but in this form it's already filled with data and I'll get an exception if I try to add a column.
The one thing I can do is Matrix.Clear() and then I'm able to add my column, but I've lost all my data...
Form.Items.Item.Refresh() doesn't work... 😔
Form.Update() doesn't work... 😔
Matrix.LoadFromDataSource() doesn't work... 😔
It handles "Stock management > Initial quantities, stock tracking, and stock posting > StockTaking" (Form 840)
Does anybody know a solution?
