“We have installed FEFO Lot Assignments SuiteApp and configured the same. However, when we click “Assign and Fulfil” button in Sales Order, we are getting an error message, “The script for assignment and fulfillment failed. Please try again.” Could you please check and let me know what function hinders the running of script or where I have gone wrong in configuration?
When we try to fulfill from the Assign and Fulfill page, we will get this error

Other Information:
When we hit “Assign and Fulfil” button the script FEFO_MR_Lot_Allocation runs in the background. We have set FEFO Preference, FEFO Shelf Life group, FEFO Commit Group, and Set Minimum fulfillment percentage in customer record.”
