• What is the cause and solution for SAP error message RSQBW454 - Field type in InfoProvider: &1 ?

  The SAP error message RSQBW454 typically indicates an issue with the field type in an InfoProvider, particularly in the context of SAP BW (Business Warehouse). This error can occur when there is a mismatch between the expected data type of a field and the actual data type defined in the InfoProvider.
  Cause:
  
  Data Type Mismatch: The field type defined in the InfoProvider does not match the data type of the source data. For example, if the InfoProvider expects a numeric field but receives a character field, this error may occur.
  Changes in Data Source: If there have been changes in the underlying data source (like a database table or a data source in SAP BW), the InfoProvider may not be updated accordingly, leading to inconsistencies.
  Incorrect Mapping: If the mapping of fields from the source to the InfoProvider is incorrect, it can lead to this error.
  Data Model Changes: Changes in the data model, such as adding or modifying fields, can also lead to this error if the InfoProvider is not updated to reflect these changes.
  
  Solution:
  
  Check Field Definitions: Review the field definitions in the InfoProvider and ensure that they match the data types of the source fields. You can do this by going to the InfoProvider in the SAP BW modeling tools and checking the field properties.
  Update InfoProvider: If there have been changes in the source data structure, update the InfoProvider to reflect these changes. This may involve re-mapping fields or adjusting data types.
  Data Source Check: Verify the data source to ensure that it is correctly defined and that the data types are as expected. If necessary, adjust the data source settings.
  Re-activate InfoProvider: Sometimes, simply re-activating the InfoProvider can resolve the issue. This can be done in the SAP BW modeling environment.
  Check for Transport Issues: If the InfoProvider was transported from one system to another, ensure that all related objects were transported correctly and that there are no inconsistencies.
  
  Related Information:
