  The SAP error message /STMC/CR_MSG779 indicates that there is an issue with processing a request due to a missing read request. This error typically occurs in the context of data transfer processes, particularly in SAP systems that involve data extraction, transformation, and loading (ETL) operations, such as SAP BW (Business Warehouse) or SAP HANA.
  Cause:
  The error message suggests that the system is trying to process a request but cannot find the necessary read request associated with the data source (ds) and data package (dp) specified in the error message. This can happen due to several reasons:
  
  Missing Data Request: The data request that the system is trying to access may not exist or may have been deleted.
  Inconsistent Data State: There may be inconsistencies in the data state, possibly due to failed data loads or incomplete processes.
  Configuration Issues: There could be configuration issues in the data source or data transfer process that prevent the system from locating the required read request.
  Transport Issues: If the system has recently undergone a transport, the necessary objects may not have been transported correctly.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check Data Requests: Verify if the data request associated with the specified data source and data package exists. You can do this by checking the relevant InfoProvider or data source in the SAP BW system.
  
  
  Reprocess the Data Load: If the data request is missing, you may need to reprocess the data load for the relevant data source. This can be done by executing the data load process again.
  
  
  Check for Inconsistencies: Use transaction codes like RSA1 (Data Warehousing Workbench) to check for inconsistencies in the data model or data requests. You can also use the RSMO transaction to monitor and manage data loads.
  
  
  Review Logs: Check the logs for any additional error messages or warnings that may provide more context about the issue. This can help identify if there are other underlying problems.
  
  
  Configuration Review: Review the configuration settings for the data source and data transfer process to ensure everything is set up correctly.
  
  
  Transport Check: If the issue arose after a transport, verify that all necessary objects were transported correctly and that there are no missing components.
