LE_SHP_DELIVERY_PROC BAdi implementation - capture delivery item change

Hi Community Members,

I am recently working on enhancement which is going to forbid quantity changes for delivery line items

if corresponding PO line item is blocked or deleted.

To do this I want to use BAdi LE_SHP_DELIVERY_PROC (Enhancements in Delivery Processing)

One of methods PUBLISH_DELIVERY_ITEM imports 2 internal tables:

IT_XLIPS Current Status of Delivery Items

IT_YLIPS Database Status: Delivery Items

Inside the method I am checking if recent quantity value (IT_XLIPS-LFIMG) is not equal to the one from database (IT_YLIPS-LFIMG). If so then I throw error.

Everything is ok, but I have encountered a strange behavior.

For example when I change delivery item quantity (LFIMG, for example 1->2 ) and then go back to the initial value (2->1)...

The problem is that when entering the method (debugger) I can see inside IT_XLIPS that LFIMG is updated, but Gross/Net weigth and volume fields still have old values (NTGEW, BRGEW, VOLUM).

That is a problem because highly possible is that after quantity field customer will also want to validate weight and volume fields.

Moreover I also checked FILL_DELIVERY_ITEM and CHANGE_DELIVERY_ITEM methods of BAdi mentioned. In all of them weight/volume (and probably other fields also) behave the same.

Could you share your comments on this issue please?

What would you recommend to do to enable such validation?

Kind Regards,

Piotr.
