How can i enhance the Performance of my customise MB5S report with posting dates.?

[bilal_zafar]

I have made a Customize report of MB5S to get the data with respect to posting dates but its taking too much time to show the result .

The Report is in 2 parts 1st is the customized Copy of MB5S and the other is my customize report . i am passing selection parameters from my report to the copy of MB5S to get the data then further process it with some formulas in my report to get the desire output .
Its working fine just the thing is its taking too much time . can any expert please tell me which part i did wrong , which cause more time consumption.
