I checked the issue raised by the MPC team regarding the new items that are not created in JDA. The FTP server was checked if the received file was not zero, as per checking there is a file on the FTP server, but it was not processed, open the file and check the items. Run the Muji inbound masterfile shell script to process the file. I validated the items in the temp table and asked for assistance from Sir Rey to manually trigger the update on the JDA side. As per confirmation from the MPC team, the item is now in JDA and this is now OK. I monitored the issue until they were able to process the PO.
