• What is the cause and solution for SAP error message /ISDFPS/FDP477 - Validity periods of selected positions do not overlap ?

  The SAP error message /ISDFPS/FDP477 Validity periods of selected positions do not overlap typically occurs in the context of SAP's Flexible Real Estate Management (RE-FX) module or similar applications where position management is involved. This error indicates that the validity periods of the selected positions do not intersect, meaning that the time frames for the positions you are trying to work with do not align.
  Cause:
  
  
  Non-Overlapping Validity Periods: The primary cause of this error is that the validity periods of the positions you are trying to process (e.g., for a contract, lease, or other real estate-related transactions) do not overlap. For example, if one position is valid from January 1, 2023, to December 31, 2023, and another is valid from January 1, 2024, to December 31, 2024, they do not overlap.
  
  
  Incorrect Data Entry: There may be an error in how the validity periods were entered or configured in the system.
  
  
  Data Consistency Issues: There could be inconsistencies in the data due to changes made in the system that have not been properly reflected across all relevant records.
  
  
  Solution:
  
  
  Check Validity Periods: Review the validity periods of the positions you are trying to process. Ensure that at least one date range overlaps with another. You can do this by navigating to the relevant transaction or report in SAP and checking the details of the positions.
  
  
  Adjust Validity Periods: If the periods do not overlap, you may need to adjust the validity dates of one or both positions to ensure they intersect. This can involve changing the start or end dates to create an overlap.
  
  
  Data Correction: If the validity periods are correct but still causing issues, check for any data inconsistencies or errors in the database. You may need to correct any discrepancies.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on managing validity periods in the context of your specific application.
  
  
  Seek Help from SAP Support: If you are unable to resolve the issue, consider reaching out to SAP support or your internal SAP team for assistance. They may have additional tools or insights to help troubleshoot the problem.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes in SAP that pertain to position management and validity periods, such as RECN (for contract management) or REIS (for real estate management).
  User Roles and Permissions: Ensure that you have the necessary permissions to view and edit the positions and their validity periods.
  Training and Documentation: Consider additional training or reviewing documentation related to the RE-FX module or the specific area of SAP you are working with to better understand how validity periods are managed.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to resolve it.
