Dump in Smartforms

Hi Experts,

I am working on smartforms and I am using period as an input criteria for some Ledger Outputs.

For few periods say like 1 to 12 its giving me correct output but when period changes to say 7 to 9 then I am getting dump in smartform output.

Means for few periods its giving correct output for few periods its giving dump screen.

Please help to solve this. Below is the dump screen error analysis

Thanks inadvance.

Thanks,
