• What is the cause and solution for SAP error message MPE_RTG_UI171 - BOM item &1 is assigned outside its effectivity ?

  The SAP error message MPE_RTG_UI171 indicates that a Bill of Materials (BOM) item is assigned outside its effectivity period. This typically occurs when the BOM item is not valid for the specified date or period in which you are trying to use it. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause
  
  Effectivity Dates: Each BOM item can have specific start and end dates that define when it is valid. If you are trying to use a BOM item that is outside of these dates, you will encounter this error.
  Configuration Issues: There may be a misconfiguration in the BOM settings or the item master data that leads to incorrect effectivity dates.
  Data Entry Errors: Incorrect data entry when creating or modifying the BOM can lead to effectivity dates being set incorrectly.
  
  Solution
  
  
  Check Effectivity Dates:
  
  Go to the BOM in question and check the effectivity dates for the item. Ensure that the current date falls within the valid range.
  If the dates are incorrect, you may need to adjust them to include the current date or the date you are trying to use the BOM.
  
  
  
  Modify BOM Item:
  
  If the BOM item is indeed valid but the effectivity dates are not set correctly, you can modify the BOM item to correct the effectivity dates.
  Use transaction code CS02 (Change BOM) to make the necessary adjustments.
  
  
  
  Review BOM Configuration:
  
  Ensure that the BOM configuration is set up correctly. This includes checking the item category and ensuring that it is appropriate for the type of BOM you are using.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help files related to BOM management and effectivity dates for further guidance.
  
  
  
  Check for Related BOMs:
  
  If the BOM item is part of a larger assembly or has dependencies, ensure that all related BOMs are also valid and correctly configured.
  
  
  
  Related Information
  
  Transaction Codes:
  
  CS01: Create BOM
  CS02: Change BOM
  CS03: Display BOM

  SAP Notes: Check for any relevant SAP Notes that may address known issues or bugs related to BOM effectivity.
  User Roles and Authorizations: Ensure that you have the necessary permissions to modify BOMs and their effectivity settings.
  
  Conclusion
  To resolve the MPE_RTG_UI171 error, you need to ensure that the BOM item is valid for the date you are working with.
