• What is the cause and solution for SAP error message MILL_MM_OB028 - Original batch purity rule (rule &1) breached --> New batch determination ?

  The SAP error message MILL_MM_OB028 indicates that the original batch purity rule has been breached during the batch determination process. This typically occurs in the context of batch management in SAP, particularly in industries like chemicals, pharmaceuticals, or food production, where the purity or quality of batches is critical.
  Cause:
  The error arises when the system attempts to determine a batch for a material, but the selected batch does not meet the purity requirements defined in the batch management settings. This can happen due to:
  
  Purity Rules Configuration: The purity rules for the material may not be correctly configured or may not align with the characteristics of the available batches.
  Batch Characteristics: The characteristics of the available batches (e.g., purity percentage) do not meet the requirements set in the original batch purity rule.
  Batch Selection Criteria: The criteria used for batch selection may be too strict or not aligned with the available batches.
  
  Solution:
  To resolve the MILL_MM_OB028 error, you can take the following steps:
  
  
  Review Purity Rules:
  
  Check the purity rules defined for the material in the batch management settings. Ensure that they are correctly configured and reflect the actual requirements.
  
  
  
  Check Batch Characteristics:
  
  Review the characteristics of the batches available for selection. Ensure that at least one batch meets the purity requirements specified in the rules.
  
  
  
  Adjust Batch Selection Criteria:
  
  If the batch selection criteria are too strict, consider adjusting them to allow for a broader selection of batches that may still meet the quality standards.
  
  
  
  Batch Creation:
  
  If no existing batches meet the purity requirements, you may need to create a new batch that complies with the purity rules.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for detailed guidance on configuring batch management and purity rules.
