Fixed Asset What -if Depreciation analysis

Content

While editing the What -if Depreciation data model , I noticed that we need to enter " *&l_fa_whatif_rep_t " which I understand must be the table name in the code. 
Is the reference to this a process_id of the Prepare what-if depreciation or What if depreciation processes ? 
I tried to give both but it ended up giving me an error " Invalid table name ". 
What should be entered in here to update/ edit the data model?
