V4126 - Details

• The SAP error message V4126, "There can only be one valid engineering change status per delivery date," typically occurs in the context of managing engineering change management (ECM) within the SAP system, particularly when dealing with materials that have multiple engineering change statuses.
  
  Cause:
  This error arises when there are multiple engineering change statuses assigned to a material for the same delivery date. In SAP, each delivery date can only have one valid engineering change status to ensure consistency and clarity in the production and delivery processes. If the system detects more than one status for the same date, it triggers this error.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Engineering Change Statuses: Review the engineering change statuses assigned to the material in question. You can do this by navigating to the relevant transaction codes (like MM03 for material master) and checking the engineering change management section.
