Wrong relevant product instance in SMSY

Hello,

we're on Solution Manager 7.1 SPS7 (SAPKB70211) and I have got a problem with a system in SMSY.

System was connected through RZ70/SLD - LMDB - SMSY.

System appears in SMSY correctly as product system SAP ERP Enhance Package (EHP6 for SAP ERP).

But in product instance selection the product instance "Discrete Ind. & Mill Products" is marked as relevant.

Ususally "ABAP Technology for ERP EHP6" should be marked, but I can't find any option to change this mapping.

If I go into change mode, system switches into LMDB, where I can't find the solution for this problem.

So my question is: how do I change relevant product instance in SMSY / LMDB?

Regards,

Julia
