Hello everyone
I have a form which is associated to an UDO
The form has 4 tabs, each of them has a matrix; the udo has 4 child tables and each matrix is bound to one of these tables...
at the beginning every table is empty, when i try to add a line in the first matrix (which is bound to Table1) and click update it gives me an error which says that can not insert an entry with DocNum = null in Table2 ....
Apparently when i click update it takes all four datasources and tries to insert them in the database and since three of them have no lines
Any ideas of how can i prevent it updating the database with other datasources that i dont use??
