• What is the cause and solution for SAP error message MPE_CM_EFFECTIVITY020 - BOM items do not have change numbers or parameter effectivity information ?

  The SAP error message MPE_CM_EFFECTIVITY020 indicates that there is an issue with the Bill of Materials (BOM) items in relation to change numbers or parameter effectivity information. This error typically arises when you are trying to perform operations that require effectivity data, such as creating or modifying BOMs, and the necessary effectivity information is missing.
  Cause:
  
  Missing Change Numbers: The BOM items do not have associated change numbers. Change numbers are used to track changes in BOMs and other master data.
  Lack of Parameter Effectivity: The BOM items may not have parameter effectivity information defined, which is necessary for certain configurations or production scenarios.
  Incorrect Configuration: The configuration settings for the BOM or the material may not be set up correctly to handle effectivity.
  Data Inconsistencies: There may be inconsistencies in the data related to the BOM or the materials involved.
  
  Solution:
  
  Check BOM Items: Review the BOM items in question to ensure that they have the necessary change numbers assigned. You can do this by navigating to the BOM in the SAP system and checking the details of each item.
  Assign Change Numbers: If the BOM items do not have change numbers, you can assign them by creating a change number in the system and linking it to the relevant BOM items.
  Define Parameter Effectivity: If parameter effectivity is required, ensure that it is defined for the BOM items. This can be done in the BOM configuration settings.
  Review Configuration Settings: Check the configuration settings for the BOM and the material to ensure they are set up to handle effectivity correctly.
  Data Consistency Check: Perform a data consistency check to identify any discrepancies in the BOM or material data that may be causing the issue.
  
  Related Information:
  
  Transaction Codes: You may use transaction codes like CS01 (Create BOM), CS02 (Change BOM), and CS03 (Display BOM) to manage BOMs.
  Change Management: Familiarize yourself with the change management process in SAP, including how to create and manage change numbers.
  Effectivity Management: Understand how effectivity works in SAP, including the different types of effectivity (e.g., time-based, parameter-based) and how to implement them in BOMs.
  SAP Documentation: Refer to SAP Help documentation for detailed guidance on BOM management and effectivity settings.
  
  By following these steps, you should be able to resolve the MPE_CM_EFFECTIVITY020 error and ensure that your BOM items are properly configured with the necessary change numbers and effectivity information.
