Stock determination with multiple storage locations

Dear Friends,

Kindly suggest how to do the following configuration in Stock

Determination.

The scenario is

For example Unrestricted Stock existing for material " X":

Plant 4000: 10 Qty

Sloc1 -- 6 qty

Sloc2 -- 4 qty

There is sales order (only plant is specified in Sales Order, No sloc) for 7 Pcs when the stock determination process is carried out it is showing the stock available is 10 qty. But when they make the PGI it is picking only 6, ie., from SLOC1, but it is not picking the balance 1 qty from SLOC2 even

though the material is available.

The same problem exists for Production order also.

Thanks,

Regards.

Krishnan.
