batch activation log showing inbound delivery which is processed completely

Hi Gurus,

We are trying to activate the batch activation for non batch managed material.The log shows that the inbound deliveries for PO are open although they are done with the GR.The PO qty, IBD qty and GR Qty are same.Can any one tell me why the deliveries are showing as open in MM02 batch activation display error screen,even after the IBD is completely recieved.

Regards

Govind
