GR Not updated in ECC PO from EWM

Hi,

I have a scenario where Putaway and GR was done in EWM system, but GR was not reflected in ECC system.

This is external Purchase Order scenario, where we create Purchase Order and create Inbound Delivery (IBD) in ECC and once IBD moves to EWM, we will do a Putaway and GR in EWM.

I checked Outbound queue in EWM (SMQ1), Inbound queue in ECC (SMQ2 & SMQ3) in ECC, but there were no related queues.

I see that PPF was not triggered in Inbound Delivery in EWM in PPF actions tab.

I tried checking SLG1, but cannot retrieve SLG1 as this PO was from the month of April.

Can you please check and advise how can we have GR done in ECC PO?

Thanks in advance for your help.
