Discussed with sir Rey the process of the creation of PO, and as per sir Rey, the PO to be created should have a status = 3. Checked the logs of the screen scrape and send them to sir Rey for checking where the screen scrape encountered a problem, as per sir Rey, the screen scrape might not insert the SKU. Checked the process of the screen scrape to check where the SKU is inserted. Listed the process of the screen scrape for more understanding, and while checking, found that the problem is with the updating of SHPO for inserting the PO number. While checking, executed the creation of PO, as per checking, PO still not created, and no problem in the JDA, thus suspect that the problem is on the data. Will continue the checking tomorrow.
