Error when doing PGI

Hi Experts

In VL02n I created a batch split for the materials ( 10, 9001,9002) and gave the confirmed quantities in batch( 9001,9002)

and I clicked on PGI issue

I am getting the below error

"Item 90001 not supported"

"Item 90002 not supported"

But when I save the delivery after batch split

and do the PGI I am not getting any error and transaction is getting successful

Can you please tell what I am missing here

Thanks
