• What is the cause and solution for SAP error message /UI5/APP_API150 - Parallel execution of calculation task not possible ?

  The SAP error message /UI5/APP_API150 Parallel execution of calculation task not possible typically occurs in the context of SAP Fiori applications or when using the SAP UI5 framework. This error indicates that a calculation task is being attempted to run in parallel, but the system has determined that this is not possible due to certain constraints.
  Causes:
  
  Resource Locking: The calculation task may be trying to access resources that are already locked by another process. This can happen if multiple users or processes are trying to execute the same calculation simultaneously.
  Configuration Issues: There may be configuration settings in the backend that restrict parallel execution of certain tasks.
  Data Dependencies: The calculation task may have dependencies on data that must be processed sequentially, preventing parallel execution.
  System Limitations: The underlying system may have limitations on how many parallel processes can be executed at once, especially if it is resource-intensive.
  
  Solutions:
  
  Check for Locks: Investigate if there are any locks on the resources being accessed by the calculation task. You can use transaction codes like SM12 to check for locks in the system.
  Sequential Execution: If the task cannot be executed in parallel, consider modifying the application logic to ensure that the task is executed sequentially.
  Configuration Review: Review the configuration settings related to the calculation task in the backend system. Ensure that there are no restrictions on parallel execution.
  Performance Tuning: If the task is resource-intensive, consider optimizing the calculation logic to reduce the load and allow for better resource management.
  Error Handling: Implement error handling in your application to gracefully manage situations where parallel execution is not possible.
