  The SAP error message MILL_PC125: Preceding batch missing; assign an input batch typically occurs in the context of production or batch management processes, particularly when dealing with batch input in the SAP system. This error indicates that the system is unable to find a preceding batch that is required for the current operation, which is often related to the production of goods or materials.
  Cause:
  
  
  Missing Preceding Batch: The error usually arises when the system expects a specific preceding batch to be available for processing, but it cannot find it. This can happen if:
  
  The preceding batch has not been created or recorded in the system.
  The batch has been deleted or archived.
  There is a mismatch in batch numbers or batch status.
  The production order is not correctly linked to the required batches.
  
  
  
  Configuration Issues: There may be configuration settings in the batch management or production planning modules that are not set up correctly, leading to the system not recognizing the necessary batch relationships.
  
  
  Data Entry Errors: Incorrect data entry during the creation of production orders or batch records can lead to this error.

  Ensuring that the batch is not marked as deleted or archived.
  
  
  
  Assign the Correct Batch: If the preceding batch is missing, you may need to assign a valid input batch manually. This can be done in the production order or during the goods movement process.
