SAP Error Message - Details

• Message type: E = Error

• Message class: DMEE - Messages for Data Medium Exchange Engine

• Message number: 371

• Message text: Node &1: you must define mapping using action nodes or an exit module

What causes this issue?

At least one action node has been created under node &V1&, so the only
mapping procedures that are possible are via action nodes or exit
module.

• What is the cause and solution for SAP error message DMEE371 - Node &1: you must define mapping using action nodes or an exit module ?

  The SAP error message DMEE371 indicates that there is an issue with the Data Medium Exchange (DMEE) configuration, specifically related to the mapping of nodes in the DMEE tree. This error occurs when a node in the DMEE structure does not have a defined mapping using action nodes or an exit module. Here’s a breakdown of the cause, solution, and related information for this error:
  Cause:
  
  Missing Mapping: The node specified in the error message does not have any associated action nodes or exit modules that define how data should be processed or transformed.
  Incorrect Configuration: The DMEE tree may not be properly configured, leading to nodes that are not fully defined.
  Incomplete Implementation: If you are in the process of setting up or modifying the DMEE structure, it’s possible that some nodes were left without the necessary mapping.
  
  Solution:
  
  
  Define Action Nodes:
  
  Go to the DMEE tree structure in transaction code OBPM1 (or the relevant transaction for your version).
  Locate the node indicated in the error message.
  Ensure that you have defined action nodes for this node. Action nodes are used to specify what actions should be taken with the data at that point in the tree.
  
  
  
  Use Exit Modules:
  
  If your mapping requires custom logic, consider implementing an exit module. This is a piece of ABAP code that can be called from the DMEE mapping to perform specific actions.
  You can define an exit module in the DMEE configuration and link it to the relevant node.
  
  
  
  Check Node Properties:
  
  Review the properties of the node to ensure that it is correctly set up. Make sure that it is intended to have action nodes or an exit module associated with it.
  
  
  
  Testing:
  
  After making the necessary changes, test the DMEE output again to ensure that the error is resolved.
  
  
  
  Related Information:
  
  DMEE Documentation: Refer to SAP documentation on DMEE for detailed guidance on how to configure mapping and use action nodes and exit modules.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as OBPM1 (DMEE tree maintenance) and OBPM2 (DMEE mapping).
  SAP Notes: Check for any SAP Notes related to DMEE for known issues or additional guidance.
  Community Forums: Consider visiting SAP Community forums or other user groups for insights from other users who may have encountered similar issues.
  
  By following these steps, you should be able to resolve the DMEE371 error and ensure that your DMEE configuration is correctly set up for data processing.
