Trail Balance table record updation manually

I am using AX 2012 r3. GL → Common → Trail Balance form. I want to update balance with respect to voucher no manually. How to do it? Please help.

I guess you will have to go to update the Financial dimension sets first, which are located at GL> Setup> Financial Dimensions> Financial dimension sets, when you open the form, you have the “Update Balances” button at the top of the form, update the sets first, you can batch the job to free your AX client. Then, Trial Balance is to reflect the updates.
