Bex query Percentage of overall Result

Dear Experts,

I want to get the % of overall results.

So I applied "GT % function"

I need to get % figure as Purchase value/ row wise overall results.

ex: 6900,447.59 / 7385808.74 * 100

But I get PO value % as

ex: 6900,447.59 / 14720330.65 * 100 = 46.88

I applied %CT and %RT. But nothing works according to the above report format.

Please help

Thanks,

Thilini
