Locking Data Problem

Hi guys,

I'm working with a Material Hierarchy (Main Group (MG)(0PRODH1), Group(G) (0PRODH2), Subgroup (0PRODH3) (SG) and Mat (0MATERIAL). In my Planning package I have a specific Hierarchy Node for 0MATERIAL.

I need to perform a calculation in different levels: For example:

If I use Fox Formula I can get passed a data record like:

MG, G, SG, Mat, Qty and MG, #, #, #, Qty

But If use User Exit I can only see a data record like:

MG, G, SG, Mat, Qty and Not MG, #, #, #, Qty (because in this case the Mat is # (empty).

To get around of that I put # in the Material Hierarchy for testing, but now I having problem with locking.

Is there any other solution for that?

I'll appreciate your comments.

Thank you,

Heverton
