• What is the cause and solution for SAP error message PK140 - Assignment of indep. source not poss. in case of event-driven cntrl cycle ?

  The SAP error message PK140, which states "Assignment of independent source not possible in case of event-driven control cycle," typically occurs in the context of production planning and control, particularly when dealing with event-driven control cycles in SAP.
  Cause:
  The error arises when there is an attempt to assign an independent requirement (like a planned independent requirement or PIR) to a control cycle that is set up for event-driven planning. Event-driven control cycles are designed to respond to actual consumption and production events rather than relying on independent requirements. Therefore, the system does not allow the assignment of independent sources (like PIRs) to these types of control cycles.
  Solution:
  To resolve this error, you can consider the following approaches:
  
  
  Check Control Cycle Configuration:
  
  Review the configuration of the control cycle in question. Ensure that it is set up correctly for event-driven planning and that it does not require independent requirements.
  
  
  
  Use Dependent Requirements:
  
  If you need to plan based on actual consumption, consider using dependent requirements instead of independent requirements. This aligns with the event-driven nature of the control cycle.
  
  
  
  Change Control Cycle Type:
  
  If independent requirements are necessary for your planning process, you may need to change the control cycle type to one that allows for independent source assignments. This may involve reconfiguring the control cycle settings.
  
  
  
  Review Master Data:
  
  Ensure that the master data (like material master, production version, etc.) is correctly set up and that there are no inconsistencies that could lead to this error.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for more detailed guidance on control cycles and independent requirements. This can provide insights into best practices and configuration options.
  
  
  
  Related Information:
  
  Event-Driven Control Cycle: This type of control cycle is designed to react to actual consumption and production events, making it suitable for environments where demand is highly variable.
  Independent Requirements: These are requirements that are not directly tied to the production process, such as forecasts or planned independent requirements.
  SAP Modules: This error is typically encountered in modules related to Production Planning (PP) and Material Management (MM).
  
  If the issue persists after trying the above solutions, it may be beneficial to consult with an SAP expert or your organization's SAP support team for further assistance.
