MC.1 report not considering Stock under Val. Class for Sales Order Stock

Hi Gurus,

I have a query, we have maintained a valuation class for sales order stock (XXXX) and other general val class for normal stock (YYYY).

When we run MB5L it shows the inventory under both the valuation classes (XXXX + YYYY), but when we run MC.1 it shows the inventory under general Valuation class (YYYY).

Clent expects that report MC.1 should also include inventory from both the Valuation Class.

How can we add the inventory from Val. Class for sales order stock?

Thanks in advance.

Regards,

PA W.
