• What is the cause and solution for SAP error message RSDS064 - Specify a data type ?

  The SAP error message RSDS064 ("Specify a data type") typically occurs in the context of SAP BW (Business Warehouse) when you are trying to create or modify a DataSource, and the system requires you to specify a data type for a field but it has not been provided.
  Cause:
  The error is usually caused by one of the following reasons:
  
  Missing Data Type: When defining a DataSource, you may have left the data type field blank for one or more fields.
  Incorrect Configuration: The DataSource configuration might be incomplete or incorrectly set up, leading to the system not recognizing the data type.
  Field Definition Issues: If you are using a custom DataSource or modifying an existing one, the field definitions may not be properly defined.
  
  Solution:
  To resolve the RSDS064 error, you can follow these steps:
  
  
  Check DataSource Definition:
  
  Go to the DataSource definition in the SAP BW system.
  Ensure that all fields have a specified data type. You can do this by navigating to the DataSource in the Data Warehousing Workbench (transaction code RSA1) and checking the field properties.
  
  
  
  Specify Data Types:
  
  For each field in the DataSource, make sure to select an appropriate data type (e.g., CHAR, NUMC, DATS, TIMS, etc.) from the dropdown menu.
  Save the changes after specifying the data types.
  
  
  
  Validate Field Mappings:
  
  If you are using a transformation or a DTP (Data Transfer Process), ensure that the field mappings are correctly defined and that the target fields have the correct data types.
  
  
  
  Re-activate the DataSource:
  
  After making the necessary changes, you may need to re-activate the DataSource to ensure that the changes take effect.
  
  
  
  Test the DataSource:
  
  Once the data types are specified and the DataSource is activated, test the DataSource to ensure that it works correctly without any errors.
  
  
  
  Related Information:
  
  Transaction Codes: You may use transaction codes like RSA1 (Data Warehousing Workbench) and RSO2 (DataSource Maintenance) to manage DataSources.
  Documentation: Refer to SAP Help documentation for detailed information on DataSource creation and field definitions.
  SAP Notes: Check for any relevant SAP Notes that might address specific issues related to DataSources and data types.
