• What is the cause and solution for SAP error message MDC_LOAD079 - Load is currently being created, execution not yet possible ?

  The SAP error message MDC_LOAD079, which states "Load is currently being created, execution not yet possible," typically occurs in the context of SAP HANA or SAP BW (Business Warehouse) when a data load process is already in progress, and a new load request cannot be executed until the current one is completed.
  Cause:
  
  Concurrent Load Processes: The error usually arises when there is an attempt to start a new data load while another load process is still running. SAP does not allow multiple concurrent loads for the same data target to maintain data integrity.
  Long-Running Processes: If the existing load process is taking longer than expected due to large data volumes, performance issues, or resource contention, it can lead to this error.
  Locking Mechanisms: SAP uses locking mechanisms to prevent data inconsistencies. If a load is in progress, the system locks the data target, preventing other loads from starting.
  
  Solution:
  
  Wait for Completion: The simplest solution is to wait for the current load process to complete. You can monitor the status of the load in the SAP BW or HANA monitoring tools.
  Check Load Status: Use transaction codes like RSA1 (for BW) or relevant HANA monitoring tools to check the status of the ongoing load. If it is stuck, you may need to investigate further.
  Cancel Stuck Processes: If you determine that the load process is stuck or taking too long, you may need to cancel it. This can be done through the process monitoring tools in SAP.
  Optimize Load Processes: If this error occurs frequently, consider optimizing your data load processes. This could involve:
  
  Reducing the volume of data being loaded at one time.
  Scheduling loads during off-peak hours.
  Improving performance of the data source or target.
  
  
  Review System Resources: Ensure that your SAP system has adequate resources (CPU, memory, etc.) to handle the data load processes efficiently.
  
  Related Information:
  
  Monitoring Tools: Familiarize yourself with SAP BW and HANA monitoring tools to keep track of data load processes.
  Transaction Codes: Common transaction codes for monitoring include:
  
  RSA1 for BW data loads.
  ST22 for dumps.
  SM37 for job monitoring.
  
  
  SAP Notes: Check SAP Notes for any known issues or patches related to data loading processes.
  Documentation: Review SAP documentation for best practices on data loading and performance tuning.
