  Cause:
  The error can arise due to several reasons:
  
  Missing Constant Date: The constant date that is required for reading master data is not defined in the system. This could be due to configuration issues or missing entries in the relevant tables.
  Incorrect Configuration: The data source or InfoObject may not be properly configured to include a constant date.
  Data Source Issues: The data source from which the master data is being read may not have the necessary settings or may be inactive.
  Transport Issues: If the configuration was recently transported from another system, it may not have included all necessary settings.
  
  Solution:
  To resolve the RSAU189 error, you can take the following steps:
  
  
  Check Constant Date Configuration:
