"Post Goods Receipt" is not allowed in VL32N

Hello,

I have a problem with GI in VL32N for an Inbound Delivery with several HU's.

The message I get is:

"Post Goods Receipt" is not allowed (HU  1835717)

What I have already checked:

1. The status of all HU's in this delivery seems to be correct

2. All HU's are assigned to the delivery

3. There was already an Inbound delivery created with reference to the Purchasing document (in our case Scheduling Agreement).

4. There was never a HU with the same number before in the system.

5. Inbound Delivery seems to be properly packed

Now I have no idea what to do.

Any suggestions appreciate.

Regards,

Grzegorz
