• What is the cause and solution for SAP error message RSDS103 - &1: Output length but no conversion exit defined ?

  The SAP error message RSDS103 indicates that there is an issue with the output length of a field in a DataSource, specifically that an output length is defined but no conversion exit is specified for that field. This typically occurs in the context of SAP BW (Business Warehouse) when working with DataSources and InfoObjects.
  Cause:
  The error arises when:
  
  A field in the DataSource has a defined output length, but there is no corresponding conversion exit assigned to handle the data format or conversion.
  The system expects a conversion exit to format the data correctly for reporting or storage, but it is missing.
  
  Solution:
  To resolve the RSDS103 error, you can follow these steps:
  
  
  Check the DataSource Definition:
  
  Go to the DataSource in the SAP BW system (transaction code RSA1).
  Navigate to the DataSource and check the field definitions.
  
  
  
  Assign a Conversion Exit:
  
  Identify the field that is causing the issue (the one with the output length but no conversion exit).
  Assign an appropriate conversion exit to that field. This can be done in the DataSource definition under the field properties.
  Common conversion exits include those for date formats, currency, and other specific data types.
  
  
  
  Adjust Output Length:
  
  If a conversion exit is not necessary for the field, consider adjusting the output length to match the actual data length without requiring a conversion exit.
  
  
  
  Re-activate the DataSource:
  
  After making changes, ensure to re-activate the DataSource to apply the modifications.
  
  
  
  Test the DataSource:
  
  Perform a test extraction to ensure that the error is resolved and that data is being extracted correctly.

  Conversion Exits: These are functions in SAP that allow for the conversion of data from one format to another. They are often used for fields like dates, currencies, and other formatted data types.
  DataSource: In SAP BW, a DataSource is a structure that defines how data is extracted from a source system (like SAP ERP) into the BW system.
  Field Properties: Each field in a DataSource can have properties such as data type, length, and conversion exit, which dictate how the data is handled during extraction.
