   • Description: Change the existing mapping from {POL_title}; else IMD+F+050+[4-5] to {POL_title}; else IMD+L+050+[4-5]
   • Save the profile
2. Go to Action profiles and create a new profile
   • Action: Create
   • FOLIO record type: Invoice
   • link created mapping profile to it
3. Go to Job profiles, create a new job profile and link the created action profile to it
