• What is the cause and solution for SAP error message C7075 - Overall network scheduling: Basic finish date before scheduled finish ?

  The SAP error message C7075, which states "Overall network scheduling: Basic finish date before scheduled finish," typically occurs in the context of project management and scheduling within SAP's Project System (PS) module. This error indicates that there is a conflict between the basic finish date of a network activity and its scheduled finish date.
  Cause:
  
  Basic Finish Date: This is the date that is set as the baseline for the activity, which should not be exceeded.
  Scheduled Finish Date: This is the date that the system calculates based on the current scheduling parameters and constraints.
  Conflict: The error arises when the basic finish date (the planned or baseline date) is earlier than the scheduled finish date (the calculated date), which is not permissible as it violates the scheduling logic.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Dates: Review the basic finish date and the scheduled finish date of the affected network activity. You can do this by navigating to the network activity in the SAP system.
  
  
  Adjust Dates:
  
  If the basic finish date is indeed set incorrectly, you may need to adjust it to a later date that aligns with the scheduled finish date.
  Alternatively, if the scheduled finish date is incorrect, you may need to adjust the scheduling parameters or constraints that are causing the scheduled finish date to be later than the basic finish date.
  
  
  
  Re-schedule the Network: After making the necessary adjustments, re-schedule the network to ensure that all dates are recalculated correctly. You can do this using transaction codes like CN22 (Change Network) or CN41 (Display Network).
  
  
  Check Dependencies: Ensure that there are no conflicting dependencies or constraints that might be causing the scheduling issue. This includes checking predecessor and successor relationships.
  
  
  Consult Documentation: If you are unsure about the changes, refer to SAP documentation or consult with a project management expert within your organization.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CJ20N (Project Builder), CN22 (Change Network), and CN41 (Display Network).
  SAP Notes: Check for any SAP Notes related to scheduling issues in the Project System, as they may provide additional insights or patches.
  User Roles: Ensure that you have the necessary authorizations to make changes to network activities and scheduling parameters.
  
  By following these steps, you should be able to resolve the C7075 error and ensure that your project scheduling is accurate and compliant with SAP's requirements.
