Hi, currently im trying to add some validation to my editable ALV report.
This is what i am trying to do:
1. Make EBELN field mandatory in header and line item
2. When append (method: CREATE_PURCHASE_ORDERS, in url below) a new record in header, once key in ebeln in header, press enter, it will auto populate sy-datum in header (bedat field) and ebeln in line item,

Any appropriate source for me to look into? couldnt find a suitable one
Looked through BCALV_EDIT_04
My source code can be seen in this url, in the comment section:
