  The SAP error message CNIF_PI101 ("Error while reading internal number for network &1") typically occurs in the context of Project System (PS) or Controlling (CO) modules when the system is unable to retrieve the internal number for a network or project. This can happen due to various reasons, including configuration issues, missing data, or inconsistencies in the database.
  Causes:
  
  Missing or Inconsistent Data: The internal number for the network might not be properly assigned or could be missing in the database.

  Configuration Issues: There may be issues with the configuration settings related to number ranges for networks or projects.
  Database Issues: There could be inconsistencies or corruption in the database that prevent the system from reading the internal number.
  Transport Issues: If the network was transported from one system to another, there might be issues with the transport that affect the internal number assignment.
  
  Solutions:
  
  
  Check Number Ranges: Verify the configuration of number ranges for networks in the Project System. Ensure that the number range is correctly defined and that there are available numbers.
