• What is the cause and solution for SAP error message PROD_ALLOC_SEQUENCE023 - Enter a lead time duration greater than/equal to 0 for constraint &2&1. ?

  The SAP error message PROD_ALLOC_SEQUENCE023 indicates that there is an issue with the lead time duration specified for a constraint in the production allocation process. Specifically, the error suggests that the lead time duration must be greater than or equal to zero, but the value provided is either negative or not set.
  Cause:
  
  Negative Lead Time: The lead time for a specific constraint has been set to a negative value, which is not acceptable.
  Missing Value: The lead time duration may not have been defined for the constraint, leading to a default value of zero or a negative interpretation.

  Review Master Data:
  
  Check the master data related to the production process, such as material master records, routing, and production versions, to ensure that all relevant lead times are correctly defined.

  Review SAP documentation or help resources related to production allocation and lead time settings for additional guidance.
