• What is the cause and solution for SAP error message RSDHA094 - Mapping not possible. Source field is already selected. ?

  The SAP error message RSDHA094 indicates that there is an issue with the mapping of fields in a DataSource or InfoObject. Specifically, it means that the source field you are trying to map has already been selected for another target field, which prevents the mapping from being completed.
  Cause:
  
  Duplicate Mapping: The source field is already mapped to another target field in the same transformation or mapping process.
  Incorrect Configuration: There may be a configuration issue where the same source field is being used multiple times in a way that is not allowed.
  DataSource Issues: The DataSource may have been incorrectly set up, leading to conflicts in field mappings.
  
  Solution:
  
  
  Check Existing Mappings: Review the mappings in the transformation or DataSource to see if the source field is already assigned to another target field. If it is, you will need to decide which mapping is correct and remove or adjust the other one.
  
  
  Modify the Transformation: If you find that the source field is indeed mapped to multiple target fields, you will need to modify the transformation to ensure that each source field is only mapped to one target field.
