Spool not generated when creating the TO from TR

Hello,

I am facing a issue while creating Transfer order. My scenario is like below:

1) Create Goods issue MB1A with two items

2) Create Transfer order from Material document

3) TO is created with 2 items

4) But spool is generated only for one item.

As per my analysis, the TO line item with storage unit which starts with 3* gives a spool while the second item with storage unit which starts 9* does not generate a spool.

But when I print the TO manually  in LT31, I am able to see the spool for both items.

Please help me if you have any idea.

Thanks & Regards,

Sainath
