• What is the cause and solution for SAP error message DMEE380 - Error in node &1: mapping in field &2 not permitted ?

  The SAP error message DMEE380 typically occurs in the context of the Data Medium Exchange Engine (DMEE) when there is an issue with the mapping configuration in the DMEE tree structure. This error indicates that there is an invalid mapping in a specific node of the DMEE tree, which is not permitted according to the defined rules or structure.
  Cause:
  
  Invalid Mapping: The mapping defined in the DMEE tree for a specific field is not allowed. This could be due to incorrect data types, incompatible field lengths, or trying to map a field that is not defined in the context of the node.
  Configuration Errors: There may be errors in the configuration of the DMEE tree, such as missing or incorrectly defined nodes, fields, or attributes.
  Data Structure Changes: If there have been changes to the underlying data structure (e.g., changes in the database table or data elements), the existing mapping may no longer be valid.
  
  Solution:
  
  
  Check the DMEE Tree Configuration:
  
  Go to the DMEE transaction (usually transaction code DMEE).
  Open the relevant DMEE tree and navigate to the node indicated in the error message.
  Review the mapping for the specified field and ensure that it is correctly defined and permitted.
  
  
  
  Validate Field Mappings:
  
  Ensure that the field you are trying to map is compatible with the target field in terms of data type and length.
  Check if the field is defined in the context of the node you are working with.
  
  
  
  Review Documentation:
  
  Consult the SAP documentation or help resources for DMEE to understand the specific requirements for mapping fields in the context of your configuration.
