How to read GL data in FP3.0 SDK script?

Hello,

In a separate BO,  I want to only READ  the G/L data (account number, account description & Period Total) and use for financial calculation based on business rules. And display it in a separate screen - list of accounts & period totals ( selection to be based on FinancialYear & Accounting Period)

Any of your guidance / reference on code sample is much appreciated in advance.

Best regards,

Ravi
