How To Fix CP440 - Lot-size range of alternative sequence not in range of reference op. set

SAP Error Message - Details

• Message type: E = Error

• Message class: CP - Task list messages: Core data

• Message number: 440

• Message text: Lot-size range of alternative sequence not in range of reference op. set

What causes this issue?

You referenced a reference operation set in your alternative sequence.
However, the lot size range of the sequence exceeds the lot size range
of the reference operation set by &V1&.

How to fix this error?

Check the routing and, if necessary, correct the lot size range
of the alternative sequence.
Make sure that the lot size range of the referenced operation set
includes the lot size range of the referenced sequence.

• What is the cause and solution for SAP error message CP440 - Lot-size range of alternative sequence not in range of reference op. set ?

  The SAP error message CP440, which states "Lot-size range of alternative sequence not in range of reference operation set," typically occurs in the context of production planning and control, particularly when dealing with alternative sequences in the capacity planning process.
  Cause:
  This error generally arises due to a mismatch between the lot size defined for an alternative sequence and the lot size range specified in the reference operation set (ROS). The reference operation set defines the parameters for production operations, including the lot size range that is permissible for the operations defined within it. If the lot size of the alternative sequence falls outside this defined range, SAP will trigger this error.
  Solution:
  To resolve the CP440 error, you can take the following steps:
  
  
  Check Lot Size Definitions:
  
  Go to the alternative sequence definition in the routing or production version and verify the lot size range defined for the alternative sequence.
  Compare this with the lot size range defined in the reference operation set.
  
  
  
  Adjust Lot Size Ranges:
  
  If the lot size of the alternative sequence is indeed outside the range of the reference operation set, you may need to adjust either the lot size of the alternative sequence or the lot size range in the reference operation set to ensure they are compatible.
  
  
  
  Modify Reference Operation Set:
  
  If necessary, modify the reference operation set to include the lot size range that accommodates the alternative sequence. This can be done in the configuration settings for the reference operation set.
  
  
  
  Review Production Versions:
  
  Ensure that the production version being used is correctly set up and that it references the appropriate routing and reference operation set.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help resources for additional context on how to manage lot sizes and alternative sequences.
  
  
  
  Testing:
  
  After making adjustments, test the changes by attempting to execute the process that triggered the error to ensure that it has been resolved.
  
  
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes such as C223 (to maintain alternative sequences) or C201 (to maintain routing) to make the necessary changes.
  SAP Notes: Check for any relevant SAP Notes that may provide additional insights or patches related to this error.
  User Roles: Ensure that you have the necessary authorizations to make changes to the routing and reference operation set.
  
  By following these steps, you should be able to identify the cause of the CP440 error and implement a solution to resolve it.
