SEM-BPS code

Question

Dear Friends,
Req: Varaible gets current or entered month value and the value of variable will be summed up till 012th month. It should not go > 12.  Eg: Assum the entered value = 007 and the calculation goes 008, 009, 010, 011 & 012.
In order to fullfill the customer req. Iwe need to apply the below logic.  We have done this code in SEM-BPS planning function.
DATA PER TYPE 0FISCPER3.
DATA FPER TYPE 0FISCPER3.
PER = VARV (YFROMPER).
DO.
FPER = PER + 001.
if PER > 001 AND PER <= 12.
YDPT_PRKG, PER} = {YDPT_PRKG, FPER}.
Else.
Exit.
Endif.
ENDDO.
But, this above code is not work as expected and it's executing infinite...Please look into the code and correct me if any syntex or logic issue.
Thanks in Advance for kind support.
Best Regards,
KS

Hey KS,
I'm assuming you've solved this already but if not . . .
Looking at the code below, you see to only hit the ELSE condition and hence exit if PER is not between 1 - 12.  Yet you only increment FPER so PER never changes and this loop will run forever.
Might also want to increment the total:
{YDPT_PRKG, PER} = {YDPT_PRKG, PER} + {YDPT_PRKG, FPER}.
Hope this helps.

Dan
