There is no Different Transaction. You use Item Receipt because, preliminary to getting a Bill, you need a dated transaction that puts this In Stock. Item Receipt is used for Inventory or Fulfillment of an order.
Or, you go right to Enter Bill.
If you have Item Receipt, you see it has a box to checkmark to Become the Bill = same transaction, different status, and Never Change the date.
"Item Receipts is for Item A and Item B. Vendor bill is received but is
only for Item A."
Then you either treat that as a Partial Dollar amount to pay, turning the entire Item receipt into a Bill and using Pay Bills and partially paying (use the Unshaded in Pay Bills).
Or, you need to Split the data into separate Item Receipts, preserving the original Date. Or, remove the Line Item from the original Item Receipt and make a Bill using the Original Date.
"When entering the bill against the Item
Receipt/Inventory, both items come over."
It's the Same Transaction; you just Checkmarked the Box.
"There is no way to delete or
remove Item B from the receipt being matched to the Vendor Bill."
You can remove it from the Item Receipt, and make it on its Own Transaction. Just preserve the other original info: qty and Date.
