Why the Purchase order receipt and acquisition cost adjustment events are combined together

Hi,

There are two scenarios. 

1.PO where Purchase Order Receipt and Acquisition cost Adjustment entries are getting created separately with different source PO and AP respectively (NLPU102430)

2.the acquisition cost adjustment entry for IPV and ERV is not generated as a separate entry but rather included within the Purchase Order Receipt with same source PO(NLPU102433)

Please refer below screenshots for more details.

FYI: Items and PO's are copied from each other hence there is no difference between Item setup/specifications and PO details except the Items.

Case 1

Case 2
