How To Fix CN268 - Planned independent requirements not found for &1 on &2

SAP Error Message - Details

• Message type: E = Error

• Message class: CN - Meldungen für Netzpläne

• Message number: 268

• Message text: Planned independent requirements not found for &1 on &2

What causes this issue?

You have changed the requirements date for a planned independent
requirement for material &v1&.

System Response

The system cannot determine any planned independent requirements for
the original requirements date &V2&. Therefore it cannot consume the
requirements for the old date.
Due to the change, the system has created planned independent
requirements for the new date, so that there is a risk that the
requirements may exist twice.

How to fix this error?

Check the current stock/requirements situation for material &v1&.

• What is the cause and solution for SAP error message CN268 - Planned independent requirements not found for &1 on &2 ?

  The SAP error message CN268 indicates that there are no planned independent requirements found for a specific material on a given date. This error typically arises in the context of production planning and control, particularly when working with materials that require independent requirements for planning purposes.
  Cause:
  
  Missing Independent Requirements: The most common cause is that there are no planned independent requirements (PIRs) defined for the material in question for the specified period.
  Incorrect Planning Version: The planning version being used may not have any PIRs defined.
  Date Range Issues: The date specified may fall outside the range of the defined PIRs.
  Material Master Settings: The material may not be set up correctly in the material master, or it may not be assigned to the correct planning group.
  Planning Strategy: The planning strategy assigned to the material may not be configured to generate independent requirements.
  
  Solution:
  
  
  Check Planned Independent Requirements:
  
  Go to transaction code MD61 (Create Planned Independent Requirements) or MD62 (Change Planned Independent Requirements) to verify if there are any PIRs defined for the material and the relevant period.
  If there are no PIRs, create them as necessary.
  
  
  
  Verify Planning Version:
  
  Ensure that you are using the correct planning version. You can check this in the planning settings or in the material master.
  
  
  
  Review Date Range:
  
  Check the date range of the PIRs to ensure that the date you are trying to plan for is included in the range of the existing PIRs.
  
  
  
  Material Master Configuration:
  
  Review the material master data (transaction code MM03) to ensure that the material is correctly set up for planning. Check the MRP views and ensure that the planning group is appropriate.
  
  
  
  Check Planning Strategy:
  
  Review the planning strategy assigned to the material. If the strategy does not support independent requirements, consider changing it to one that does.
  
  
  
  Run MRP:
  
  After making the necessary adjustments, run the Material Requirements Planning (MRP) process again using transaction code MD02 or MD03 to see if the error persists.

  Planning Strategies: Familiarize yourself with the different planning strategies in SAP, as they dictate how independent requirements are handled.
  Documentation: Refer to SAP Help documentation for detailed information on planned independent requirements and MRP processes.
  
  By following these steps, you should be able to identify the cause of the CN268 error and implement the necessary solutions to resolve it.
