Hello mundirwae,
I would focus on receiving a single line (delete all lines but the first on you rproduct receipt) and try to isolate the issue. Since you do not have an error message, I would look at the three most common causes. Normally each of these common issues would result in an error message explaining the cause but ...
1) Inventory Dimension is missing: Did you receive these lines with all the required Inventory Dimensions? Depending on your items could be Site, Warehouse, Location, Inventory Status, License Plate, Batch number...;
2) Missing GL account: Look at the Financial Distribution the PO line (image below) to make sure that the GL account is not missing . There would be separate lines for item, taxes and charges.
3) Any missing Financial Dimensions: talk to an Finance BA to see if there are any Account Structure or Advanced Rules that are being challenged for the GL account identified in teh Financial Distribution.
4) Might as well make sure that there are no Charges left on teh PO header. All charges have to be distributed to the lines.
