Receiving warning message when trying to process a SO using WHS process during Picking list generation.

Hi Experts,

I am receiving this warning message when trying to process a SO using WHS process during Picking list generation.

"Dimensions location level and below have been specified on the order line. Warehouse management processing can no longer be used to process this line."

For the item on the SO, the Reservation hierarchy is as mentioned below:

Site

Warehouse

Inventory Status

Batch Number

Location

License Plate

I had mentioned the batch number on the SO line. After manual reservation, while generating Picking list, I get the above mentioned error message. If I mention the location on the SO line, and generate the picklist by ignoring the error message, I am not able to release the SO line to WH for Picking. When I look at the inventory transaction for that SO line, it has status picked.

What is wrong in my processing or set up? Please help.

Thanks,

Balaji
