How to load performance documents that are in progress with competencies and current task

Hello Support,

Our current in performance document involves adding competencies and modifying the competency weightages as a first step of the performance document which will be done my the employee (Which takes place at the starting of the year), then the employee self-evaluation and manager evaluation continues at the end of the year.

Now we have to migrate the performance documents and evaluation data to a new environment, and we are not able to find the business objects to load the performance documents as per the above-mentioned process. Could you please let us know if we can load the performance documents with different competencies (and different weightages) for different employees along with the current task in the performance document using HDL.
