• What is the cause and solution for SAP error message W/157 - Material & is not to be processed as phases are already active ?

  SAP Error Message:
  
  W/157 Material & is not to be processed as phases are already active
  
  Cause:
  This warning message occurs in SAP Production Planning (PP) or Process Industries when you attempt to process a material (e.g., during production order processing, phase processing, or confirmation) but the system detects that the material already has active phases in the production process.
  In other words, the system prevents you from processing the material again because there are existing active phases (steps or operations) that have not yet been completed or closed. This is a control mechanism to avoid duplicate or conflicting processing of the same material phases.
  
  When does it typically occur?
  
  During confirmation of production orders or process orders.
  When trying to start or process phases in process industries (e.g., process orders with phases).
  When attempting to create or change phases for a material that already has active phases.
  
  
  Solution:
  
  
  Check Active Phases:
  
  Review the production or process order to identify which phases are currently active.
  Use transaction codes like CO03 (Display Production Order) or COR3 (Display Process Order) to check the status of phases.
  
  
  
  Complete or Close Active Phases:
  
  Confirm or close the active phases before attempting to process the material again.
  Use confirmation transactions (CO11N, COR6N) to confirm the phases.
  
  
  
  Avoid Duplicate Processing:
  
  Ensure that you are not trying to start or process the same phase multiple times simultaneously.
  Coordinate with production planners or operators to avoid overlapping phase processing.
  
  
  
  Check Customizing Settings:
  
  In some cases, the system behavior can be influenced by configuration in the process order or production order settings.
  Verify if any user-exits or custom validations are causing this message.
  
  
  
  
  Related Information:
  
  Message Class: W/157 is a warning message, so it does not stop processing but advises caution.
  Phases in Process Orders: Phases represent steps or operations in process industries. Managing phases correctly is crucial for accurate production tracking.
  Transactions:
  
  CO03 - Display Production Order

  Summary:
  The warning "Material & is not to be processed as phases are already active" indicates that the material you are trying to process has ongoing active phases in production. To resolve this, identify and complete the active phases before proceeding. This ensures orderly and consistent production processing without conflicts.
