• What is the cause and solution for SAP error message RSDME721 - Data type mismatch between input value and target info object ?

  The SAP error message RSDME721 indicates a data type mismatch between the input value and the target InfoObject in a query or data extraction process. This error typically occurs in SAP BW (Business Warehouse) when there is an inconsistency between the data types defined in the InfoObject and the data being passed to it.
  Cause:
  
  Data Type Mismatch: The input value being provided does not match the expected data type of the target InfoObject. For example, if the InfoObject expects a numeric value but receives a string, this error will occur.
  Incorrect Mapping: If there is a mapping issue in the transformation or data flow, it can lead to this error.
  Inconsistent Data: The data being loaded or queried may have inconsistencies, such as null values or unexpected formats.
  Changes in InfoObject Definition: If the definition of the InfoObject has been changed (e.g., changing a data type from CHAR to NUMC) without updating the related queries or transformations, this can lead to mismatches.
  
  Solution:
  
  Check Data Types: Verify the data types of the input values and the target InfoObject. Ensure that they match. You can do this by checking the InfoObject definition in the SAP BW system.
  Data Transformation: If you are using a transformation, ensure that the mapping is correct and that the data types are compatible. You may need to adjust the transformation rules to convert data types appropriately.
  Data Cleansing: Review the data being loaded or queried for any inconsistencies. Cleanse the data to ensure it adheres to the expected formats and types.
  Update Queries: If the InfoObject definition has changed, update any queries or reports that reference it to ensure they are compatible with the new definition.
  Testing: After making changes, test the data load or query execution to ensure that the error is resolved.
  
  Related Information:
  
  Transaction Codes: You can use transaction codes like RSA1 (Data Warehousing Workbench) to check InfoObjects and transformations.
  InfoObject Maintenance: Use transaction RSD1 to maintain InfoObjects and check their properties.
  Transformation Maintenance: Use transaction RSF1 to maintain transformations and ensure proper mapping.
  Data Preview: Use the data preview functionality in the InfoProvider to check the data types and values being loaded.
