Hard Commitment to Primary Location by Print Pick-slip

Hi,

When a sales order with 20 line items get hard-commited through R42520 - Print Pick-slip, 3 or 4 line items are getting hard commited to the primary location.

Points to consider:

1. Primary location holds no inventory

2. Inventory is abundantly available in secondry locations/lots

3. Lots are not held

2. Commitment attributes in the Item Master and Item B/P are same for all the 20 items

3. Commitment flag in F4211 is set to "C" for all the lines

4. Status properly updated for all the lines as set

Please advise on avoiding this.

Thanks
