User Exit/ BADI for Production Order Save

Hi Friends,

                  I need to Validate the Production order line item when production order is save.

I was gone through the User Exit-PPCO0007 and BADI-WORKORDER_UPDATE - AT_SAVE.

But here showing header level material only. I need to get component table ( Line Item).

Any one help to resolve the issue.

i need to structure like below BADI.

WORKORDER_UPDATE~BEFORE_UPDATE

Unfortunately, it is triggering after generating Production order number but i need before generation Production order number.

Thanks in advance.

Regards,
