• What is the cause and solution for SAP error message DPR_API064 - Constraints reset; project header not changed ?

  The SAP error message DPR_API064 with the description "Constraints reset; project header not changed" typically occurs in the context of SAP Project Management, particularly when working with the Project System (PS) or the Project Management (DPR) module. This error indicates that there was an attempt to change a project header, but the system has determined that the constraints associated with the project have been reset, and therefore, no changes were made to the project header.
  Causes:
  
  No Changes Made: The most common cause is that the system detected no actual changes to the project header data, which leads to the constraints being reset.
  Data Validation Issues: There may be validation rules or constraints in place that prevent changes to the project header if certain conditions are not met.
  Authorization Issues: The user may not have the necessary authorizations to make changes to the project header.
  System Configuration: There may be specific configurations or settings in the project management module that restrict changes under certain conditions.
  
  Solutions:
  
  Verify Changes: Ensure that you are making actual changes to the project header. If no changes are detected, the system will not update the header.
  Check Constraints: Review any constraints or validation rules that may be affecting the project header. Ensure that all required fields are filled out correctly and that any dependencies are satisfied.
  User Authorizations: Check if the user has the necessary authorizations to modify the project header. If not, contact your system administrator to grant the required permissions.
  Review Project Settings: Look into the project settings and configurations to see if there are any restrictions on changing the project header. This may involve consulting with a project manager or SAP consultant.
  Debugging: If the issue persists, consider using transaction codes like SE80 or SE37 to debug the function module or program that is generating this error. This may provide more insight into why the constraints are being reset.
