• What is the cause and solution for SAP error message WU400 - PP conditions "from" & cannot be after SP conditions "to" & ?

  The SAP error message WU400 typically occurs in the context of Production Planning (PP) when there is a conflict in the validity periods of conditions. Specifically, this error indicates that the "from" date of a certain condition is set to a date that is after the "to" date of another condition. This can happen in various scenarios, such as when defining pricing conditions, production versions, or other time-dependent data.
  Cause:
  
  
  Overlapping Validity Periods: The most common cause of this error is that the validity periods of two or more conditions overlap or are incorrectly defined. For example, if you have a condition that is valid from January 1 to January 31, and you try to create another condition that is valid from January 15 to February 15, the system will raise this error because the "from" date of the second condition is not valid in relation to the "to" date of the first condition.
  
  
  Incorrect Data Entry: Manual data entry errors can lead to incorrect dates being set for conditions.
  
  
  Master Data Issues: Problems with master data, such as incorrect configuration of material master records or production versions, can also lead to this error.
  
  
  Solution:
  
  
  Review Validity Periods: Check the validity periods of the conditions involved. Ensure that the "from" date of the condition in question is not set to a date that is after the "to" date of another condition. Adjust the dates accordingly.
  
  
  Adjust Conditions: If you find overlapping conditions, you may need to adjust the conditions to ensure that they do not conflict. This may involve changing the dates or removing unnecessary conditions.
  
  
  Data Consistency Check: Perform a consistency check on the relevant master data to ensure that all entries are correct and do not conflict with each other.
  
  
  Consult Documentation: If you are unsure about the correct validity periods, consult the SAP documentation or your organization's guidelines for setting up conditions in the PP module.
  
  
  Testing: After making adjustments, test the changes in a development or test environment before applying them to the production environment to ensure that the error is resolved.
