OTL: Project and Grants added to OTL

 Hello Guru's

I have a requirement to add process and grants data to an existing OTL query.  The query doesn't return any value, however I know that it should.. Does anyone have an example I can leverage? Here is what I've done so far

SELECT htg.tk_group_name group_name,

    papf.full_name full_name,

         htb.start_time,

     htb.stop_time,

     initcap(TO_CHAR(htb.start_time,'DAY')) DAYY,

    tbb_det.approval_status approval_status,

    element_name Hours_Type,

    SUM(tbb_det.measure) monday_tot_hrs,

    0 tuesday_tot_hrs,

    0 wednesday_tot_hrs,

    0 thursday_tot_hrs,

    0 Friday_tot_hrs,

    0 Saturday_tot_hrs,
