Populate report from date to date for many ID

Hello
I search for macro to deal for each sheet .
in two sheets I have data for items in columns D:F and the price in column H . so what I want when merge duplicates items based on matching columns D: F and when repeat the same item with different price should use price averages but when merge items should be separated for each sheet alone , also when merge quantity should just be for SVR sheet (means ignoring QTY totally in SR sheet when merge as I did last sheet .
when merge data should be based on two cells (dates) should merge within two dates in E2,G2 . if the E2,G2 are empty then should be empty from row 5 .every time run the macro should clear data from row5 before brings the data without delete formatting and borders , not repeat to the bottom the same data have already copied.
in REPORT sheet SVR header is averages prices from column H for SVR sheet ,SR header is averages prices from column H for SR sheet and in last row(TOTAL) should sum the columns I,J,K and in column L will subtract and sum for I:K as I put the formulas .
if they data are existed in SVR but not in SR should show in REPORT sheet , but if they data are existed in SR ,not in SVR should NOT show in REPORT sheet .
finally when copy data to report sheet I want keep the formatting (numbers,borders....) .
thanks
