• What is the cause and solution for SAP error message RSDHA357 - Field '&1' is not mapped ?

  The SAP error message RSDHA357, which states "Field '&1' is not mapped," typically occurs in the context of SAP BW (Business Warehouse) when there is an issue with the mapping of fields in a DataSource or InfoObject. This error indicates that a field in the data source is not correctly mapped to the corresponding field in the target InfoObject or DataStore Object (DSO).
  Cause:
  
  Field Mapping Issues: The field in question (represented by '&1') is not defined in the target structure or is not correctly mapped in the transformation rules.
  Changes in DataSource: If the DataSource has been modified (e.g., fields added or removed) after the transformation was created, it may lead to this error.
  Inconsistent Data Model: The data model may have inconsistencies, such as missing InfoObjects or incorrect data types.
  Transport Issues: If the transport of objects was not successful, it could lead to missing mappings.
  
  Solution:
  
  
  Check Field Mapping:
  
  Go to the transformation that is causing the error and check the mapping of fields. Ensure that all fields from the source are correctly mapped to the target InfoObjects.
  If the field is not needed, you can remove it from the transformation.
  
  
  
  Update Transformation:
  
  If the DataSource has changed, you may need to update the transformation to reflect the new structure. This can be done by reassigning the fields or creating a new transformation.
  
  
  
  Validate DataSource:
  
  Check the DataSource in the Data Warehousing Workbench (transaction RSA1) to ensure that all fields are correctly defined and active.
  
  
  
  Check InfoObjects:
  
  Ensure that the InfoObjects that are supposed to receive the data are active and correctly defined in the system.
  
  
  
  Transport Check:
  
  If the issue arose after a transport, check if all necessary objects were transported correctly. You may need to re-transport or adjust the objects in the target system.
  
  
  
  Testing:
  
  After making the necessary changes, test the data load again to ensure that the error is resolved.
