Problem during goods issue to production order using MB1A with 261 mov. type

Hi Gurus,

I have an issue in MB1A transaction when issuing material to production order with movement type 261.

For one raw material I have maintained alternative unit of measure as 10000 Meter = 1 No. (NO is the base unit) in basic data 1 view.

I have maintained the unit of issue also in plant data/storage location 1 view as M. In finished goods BOM I have maintained the qty for this component as 85 M. (actually alternative unit of measure "M" is automatically picked from unit of issue maintained in material master).

The issue is, when I do MB1A against the order, for this particular material, the qty is picking as 10000M instead of 85 M.

Can anyone suggest solution for this issue. We are struck with this issue for our configuration testing.

Thanks and regards
