Hi Abhishek,
If you create the inbound delivery against PO , you can get the document type 'INB' and against that option is there for 'Determination Procedure for Packaging Material Proposal'.
But for expected goods receipt , you can do the physical goods receipt against the EGRE document and once you save that, IBD can be generated.
here for EGRE process document type is 'EGRE' and there is no option for 'Determination Procedure for Packaging Material Proposal'.
for better under standing, please go through the below paths to compare both.
