I have a requirement where I click on a custom application bar from my selection screen and it should got through a new transaction(zt1) selection screen, should pass the delivery number from my base program, should execute automatically. when executed it displays some ALV line items. Automatically those line items should be selected(I have a select all button) and should click on a custom application button(Print).
How can I achieve this? I have an option of BDC but any other choices apart from that?
