• What is the cause and solution for SAP error message DMEE_PAYMFORMAT138 - Name of customer format mapping has to begin with "/" ?

  The SAP error message DMEE_PAYMFORMAT138 indicates that there is an issue with the naming convention of a customer format mapping in the DMEE (Data Medium Exchange Engine) configuration. Specifically, the error states that the name of the customer format mapping must begin with a forward slash ("/"). 
  Cause:
  
  Incorrect Naming Convention: The name of the customer format mapping you are trying to use does not start with a forward slash. In SAP DMEE, custom format mappings must adhere to specific naming conventions, and one of those conventions is that the name must begin with a "/".
  
  Solution:
  
  
  Rename the Format Mapping: 
  
  Go to the DMEE configuration transaction (usually transaction code DMEE).
  Locate the customer format mapping that is causing the error.
  Edit the name of the format mapping to ensure it starts with a forward slash (e.g., change MyFormat to /MyFormat).
  Save the changes.
  
  
  
  Check Other Configurations: After renaming, ensure that any references to this format mapping in your payment medium configuration or other related areas are updated accordingly.
