  The SAP error message RSM1057, which states "Initialization for Data Source &1 Can Not Be Deleted in Source System &2," typically occurs in the context of SAP BW (Business Warehouse) when there is an issue with the initialization of a data source. This error can arise during the process of data extraction from a source system, particularly when trying to delete or reset the initialization for a data source that is still in use or has dependencies.
  Causes:
  
  Active Data Source: The data source you are trying to delete or reset is still active or has been used in a data load process.
  Open Requests: There may be open requests or data loads that are still referencing the data source.
  Inconsistent State: The data source might be in an inconsistent state due to previous errors during data extraction or initialization.
  Authorization Issues: Lack of proper authorizations to delete or modify the data source in the source system.
