• What is the cause and solution for SAP error message PSS4_MSG171 - &1 &2 validity must overlap with the work package &3 validity ?

  The SAP error message PSS4_MSG171 indicates that there is a validity overlap issue between a work package and another object (like a project or task) in the system. This error typically arises in the context of project management or work package management within SAP, particularly in modules like SAP PS (Project System).
  Cause:
  The error occurs when you attempt to create or modify a validity period for an object (e.g., a work package) that does not overlap with the validity period of the associated work package. This means that the start and end dates of the new validity period do not intersect with the existing work package's validity period.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Validity Periods: Review the validity periods of both the work package and the object you are trying to create or modify. Ensure that the start and end dates of the new validity period overlap with those of the work package.
  
  
  Adjust Dates: If the validity periods do not overlap, adjust the start and/or end dates of the object you are trying to create or modify so that they fall within the range of the work package's validity period.
  
  
  Review Dependencies: Ensure that there are no other dependencies or constraints that might be affecting the validity periods. Sometimes, other related objects may have their own validity periods that need to be considered.
  
  
  Consult Documentation: If you are unsure about the validity periods or how they are defined in your specific SAP implementation, consult the relevant SAP documentation or your organization's SAP support team for guidance.
  
  
  Testing: After making the necessary adjustments, try to save or activate the object again to see if the error persists.
