F.52 Balance interest Program calculate Documents outside Calculation Period Range

Dear Experts,

Although The Configuration is maintained When I enter my G/L to Run the interest Calculation .

The System Presents Documents from Past periods although they ARE outside the Calculation Period Range which results in wrong interest Calculation

I have tried to change the Reference Key(Posting Date) to 3 the results were documents only in August.

I Don't understand why documents from Previous year and periods are chosen When I use Reference Key 1( Value date) (the correct Scenario) although previous months and other G/L accounts which we run the problem on work fine.

Kindly Advise,
