  The SAP error message WRF_PPW279, which states "Assignment does not use parallel processing due to system error," typically occurs in the context of the SAP Advanced Planning and Optimization (APO) module, particularly when dealing with planning runs that involve parallel processing.
  Cause:
  The error can be caused by several factors, including:
  
  System Configuration Issues: There may be misconfigurations in the system settings that prevent parallel processing from being utilized.
  Resource Limitations: The system may not have enough resources (e.g., memory, CPU) available to execute parallel processing.
  Data Issues: There may be inconsistencies or issues with the data being processed that prevent the system from executing the task in parallel.
  Locks or Deadlocks: Other processes may be locking resources that are needed for parallel processing, leading to this error.
  Software Bugs: There may be bugs in the version of SAP you are using that affect parallel processing capabilities.
  
  Solution:
  To resolve the WRF_PPW279 error, you can take the following steps:
