No item type determined for lower-level item (OUTB DLG) error in SMQ2

[NV97]

Hello,

When I maintain the complete delivery indicator in ERP delivery and trigger to EWM, its stuck in smq2 with error "No item type determined for lower-level item (OUTB DLG)". If I don't maintain the indicator, the queue is processed, and deliveries are received in EWM. 

I have activated delivery split at delivery type level. let me know what the possible reasons could be?

Thanks!
