What is the issue?

 Importing Supplier from IP does not show any suppliers to import even if there are suppliers available in IP.

Resolution:

• Check SUPPLIERSBYCOMPANIES parameter on both IP Admin and PM Admin and check whether the values are identical.
• If both the  values are not identical then make them identical.
   
   Example: If the parameter SUPPLIERSBYCOMPANIES value is 'True' in IP Admin then it should be 'True' in PM Admin as well and vice versa.
   In other case if both the values are not same in IP and PM i.e. IP has value 'TRUE' but PM has 'FALSE'  or vice versa then user will not be able to import suppliers from IP (Invoice Processing).
