Executed the creation of PO and checked if there is a created PO now, as per checking, there is no PO created, though when checking the SKUs, all of selling U/M and buying U/M have value. Advised Ms. Kristine that this will be checked again, as the PO is not created. Checked the web application again, by testing it on the JDA test environment by replicating the data from prod to test, and as per checking, all the invoice with their SKUs has no problem and when checked the PO, it is created. Executed the PO creation in prod again, and checked the data, as per checking, the PO has been created in the invoice and on the SKU under it. Advised Ms. Kristine that it is now ok.
