Some staff of our company does not have access to tFlow (admin, sales, etc.) but it does to PJM. This case is for our Sales Reps, they have access to PJM and can create orders and estimates. When an order is created they can upload a file and finally create the job.
This job arrives at tFlow, and it will analyze the file. If for some reason the files are wrong or something is missing on the file, PJM allows me to delete it and then upload again the correct one. But tFlow will not receive the last file updated.
This could also apply to Pressero.
