Ad-Hoc Query Field using HR_99S_INTERVAL_BETWEEN_DATES function module

Question

I have created an additional field in Sq02 to calculate years between two dates and am using function module HR_99S_INTERVAL_BETWEEN_DATES.
There are no syntax erros but when I run a query in Sq01 and output the field it doesn't calculate instead gives "00000" output.
The field Code in the additional field
Clear ZHR_SERVICEYRS.
DATA: V_MONTHS TYPE  i.
DATA: V_YEARS TYPE  i.
DATA: V_MONTHS1 TYPE  char20.
DATA: V_YEARS1 TYPE  char20.
CALL FUNCTION 'HR_99S_INTERVAL_BETWEEN_DATES'
  EXPORTING
   BEGDA           = P0002-GBDAT
   ENDDA           = Sy-Datum
  TAB_MODE        = ' '
IMPORTING
  DAYS            =
  C_WEEKS         =
   C_MONTHS        = V_MONTHS
   C_YEARS         = V_YEARS
  WEEKS           =
  MONTHS          =
  YEARS           =
  D_MONTHS        =
  MONTH_TAB       =
V_MONTHS1 = V_MONTHS.
V_YEARS1 =  V_YEARS.
CONCATENATE V_YEARS1  '.'  V_MONTHS1 INTO ZHR_SERVICEYRS.
condense ZHR_SERVICEYRS.

Hi Anuj,
Yes, you use Transaction Code SQ02.  Find your infoset on the list - if you want to create a new infoset you can do so.  If it is an existing infoset, select it and Change.  On the next screen you will see all the infotypes in that infoset on the left.  The fields available for Ad Hoc are on the right.  Open the infotype table on the left and the field group on the right.  If the field is not included in the field group all you have to do is drag and drop from the list on the left to the correct field group.  If the infotype is not already in your infoset, select Edit --> Change Infotype Selection from the top menu bar.  Place a check in the new infotype and then return and do the drag and drop if necessary.  You will find the basic fields already moved to the field group. 
You say you want information from IT0008-Basic Pay and IT1005-Planned Compensation.  Problem is that if you use the standard HR logical data base, there is no link directly between a person and IT1005.  IT1005 is assigned to a Position or a Job.  If it is assigned to a Position, you can select the "Change Infotype Selection" action and ago to the bottom of the list to Related Objects.  Here select Position and open that to find the IT1005.  If the IT1005 is tied to the Job, there is no direct link. Thus, if it does not already exist, you will need to create an infoset based on the PCH logical database and object Position.  Now you can link that Position to "Holder"-Person and "Described by"-Job.  Again, select the infotypes and fields you want and you will be able to obtain your information via Ad Hoc Query based on that infoset.
