• What is the cause and solution for SAP error message KM020 - Period(s) to be changed must include all of the period of validity ?

  The SAP error message KM020 ("Period(s) to be changed must include all of the period of validity") typically occurs in the context of SAP Controlling (CO) when you are trying to change a period or a set of periods in a transaction that requires the entire validity period to be included in the change.
  Cause:
  This error usually arises when:
  
  You are attempting to change a period that does not encompass the entire validity range of the object you are working with (e.g., a cost center, internal order, or other controlling objects).
  The periods you selected for the change do not cover the full range of the validity period defined for the object in question.
  
  Solution:
  To resolve the KM020 error, you can take the following steps:
  
  
  Check Validity Period: Verify the validity period of the object you are trying to change. You can do this by navigating to the relevant master data (e.g., cost center master data) and checking the validity dates.
  
  
  Select Correct Periods: Ensure that the periods you are trying to change include the entire validity period. If the validity period is from January to December, you must select all months within that range.
  
  
  Adjust Periods: If you need to change only specific periods, you may need to adjust the validity period of the object first, if that is permissible in your business process.
  
  
  Consult Documentation: Review the SAP documentation or help files related to the specific transaction you are using to understand the requirements for changing periods.
  
  
  User Authorization: Ensure that you have the necessary authorizations to make changes to the periods in question.
