PCR for Quota Generation

Hi Gurus,

I have to modify a pcr written for absence quota generation in +ve Time Mgt. as per the client requirement. The pcr structure looks like:

ZQ01

  *

     ****

         HRS=BCURMO Set

         HRS?10            Decision op.  HRS

in the above piece of pcr, I want to know, whether HRS?10 checks the payroll month or calendar month (whether 10 is OCTOBER month or January month) ?

I also found few liness like:

OUTAQTYP

    * *

       20

          HRS=FR     F

          ADDDB8100    

          HRS=FC     F

          ADDDB8101

          HRS=FE     F

          ADDDB8102

          HRS=01

          ADDDB9001

In above lines, I want to know, what is the meaning of HRS=FR  F and HRS=FC  F (also HRS=FE  F).

I searched the entire scn forum. But I am not able to locate anything related to this.

Please provide any link/doc related to this.

thanks in advance.

regards

Raj.
