Why PO Item does not appear when return GR?

Question

Dear Gurus,
The scenerio is,
A standard PO with 30 items.
The PO is released and complete received by MB01 103, 105.
When return GR by MIGO GR 122, the PO items do not appear except one item. If use MB01, the same.
Why? Pls advice. Thanks.

Just found a good OSS note: Note 886735 - MIGO: Unclear why GR is not possible for the purchase order
It has a report attached, that helps to analyse the reason.
Carry out the following checks using the report:
1.  Check the document category
Information: The document category 'F' is possible for purchase orders and the document category 'L' is possible for scheduling agreements.
2.  Check that the purchase order/scheduling agreement is not deleted.
3.  Check that the purchase order/scheduling agreement is not blocked.
4.  Check whether the purchase order/scheduling agreement is released.
5.  Check that the purchase order is not held.
6.  Check whether the goods receipt is already posted.
7.  Is there a purchase order for external service?
8.  Is there a blanket purchase order?
9.  Is there a text item?
10. Is there a statistical item?
11. Is the goods receipt indicator set in the purchase order/scheduling agreement?
12. Check whether the confirmation control is active and whether a confirmation is still not available.
13. Is there a valid scheduling agreement delivery schedule line?
