• What is the cause and solution for SAP error message RSDHA392 - Data type '&1' of field '&2' is not valid ?

  The SAP error message RSDHA392 indicates that there is an issue with the data type of a field in a DataSource or InfoObject. Specifically, it means that the data type specified for a field is not valid or not recognized by the system. This can occur in various scenarios, such as when creating or modifying DataSources, InfoObjects, or when working with data models in SAP BW (Business Warehouse).
  Cause:
  
  Incorrect Data Type Definition: The data type defined for the field may not match the expected types in SAP BW. For example, if a field is defined as a character type but is being treated as a numeric type, this error may occur.
  Incompatibility with Source System: If the DataSource is connected to a source system that has different data type definitions, this can lead to mismatches.
  Field Length Issues: The length of the field may exceed the maximum allowed length for the specified data type.
  Changes in Data Model: If there have been recent changes to the data model or InfoObjects, it may lead to inconsistencies in data types.
  
  Solution:
  
  Check Data Type Definitions: Review the data type definitions for the field in question. Ensure that they are correctly defined and compatible with the source data.
  Adjust DataSource Settings: If the error occurs in a DataSource, check the settings and mappings in the DataSource. Make sure that the field mappings are correct and that the data types align with the source system.
  Modify InfoObject: If the field is part of an InfoObject, you may need to modify the InfoObject to correct the data type. This can be done in the InfoObject maintenance transaction (e.g., RSA1).
  Check Field Length: Ensure that the field length is appropriate for the data type being used. Adjust the length if necessary.
  Re-activate Objects: After making changes, re-activate the affected DataSource or InfoObject to ensure that the changes take effect.
  Test Data Load: After making the necessary adjustments, test the data load again to see if the error persists.
