We need a custom workflow create to achieve the following below JOB CARDS 1) Created by Production planner 2) Go to labels – Time limit needed –Warehouse manager to be informed (email) if the time elapses. 3) Go to Bulk – Time limit needed –Warehouse manager to be informed (email) if the time elapses. 4) Go to Packaging warehouse – Time limit needed –Warehouse manager to be informed (email) if the time elapses. 5) Go to factory – stock verified – Time limit needed – Production planner and Factory manager to be informed (email) if the time elapses. 6) Filling Room - Time limit needed – Factory manager to be informed (email) if the time elapses. 7) Credits back to Packaging warehouse with credit sheet – stock to be checked and transferred back into the warehouse –Warehouse manager to be informed (email) if the time elapses. 8) Filled products to label / sleeving – Time limit needed- Factory manager to be informed (email) if the time elapses. 9) Coded, shrinked and packed – Time limit needed - Production planner and Factory manager to be informed (email) if the time elapses. 10) Packed stock transfers – The job card needs to go to the person in charge of receipting in the finished goods to be checked – sent to the person issuing jobs to be issued, back to the person receipting jobs to be receipted and then possibly to the packed stock supervisor to confirm the transfer. 11) Finished job card to go back to production planner to inform him of completion of job # 6 and #8 may be reversed for certain jobs Once jobs are in the factory – time limits need to depend on the production plan – perhaps these can be set by shift supervisor? At each step the job card needs to be updated with relevant info
