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

CP440 - Overview

• 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.

CP440 - Details

• 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
