  The SAP error message RSDS125 indicates that there is a missing field of validity (lower limit) in a specific segment of a DataSource. This error typically occurs in the context of SAP BW (Business Warehouse) when working with DataSources, especially during the extraction process.
  Cause:
  The error is usually caused by one of the following issues:
  
  Missing Field Definition: The field that is expected to hold the lower limit value is not defined in the DataSource or is not correctly mapped.
  Incorrect DataSource Configuration: The DataSource may not be configured properly, leading to missing fields in the extraction structure.
  Inconsistent Data: The data being extracted may not conform to the expected structure, leading to missing values for the specified field.
  Changes in Source System: If there have been changes in the source system (like changes in the underlying database or data model), it may lead to discrepancies in the DataSource.

  To resolve the RSDS125 error, you can follow these steps:
  
  
  Check DataSource Configuration:

  Validate Source System:
  
  If the DataSource is based on a table or view in the source system, check the source system to ensure that the field exists and is populated with valid data.
  If there have been recent changes in the source system, you may need to update the DataSource in BW.
  
  
  
  Re-activate DataSource:
