Prakash, You want to "merge all the 28 item wise file in stead of merging 10 file separately 18 file separately and then merging these two to get the final data." There may be a way to do so but it is also possible to minimize the lines of code by adding another loop. Assume that you have two datasets, level3_list.dta and level4_list.dta. You can process both files by creating a loop that refers to the numbers 3 and 4. The converted datasets are subsequently merged. Friedrich local levels "3 4" foreach l of local levels { use "level`l'_list.dta", clear local vars "item_code asicc_code unit_quantity quantity value" levelsof item_code, local(items) foreach i of local items { preserve keep if item_code==`i' foreach var of varlist `vars' { ren `var' `var'_`i' } sort common_id save "item`i'.dta", replace restore } contract common_id drop _freq foreach i of local items { merge common_id using "item`i'.dta" drop _merge sort common_id } save "level`l'data.dta" } use "level3data.dta" merge common_id using "level4data.dta" On Thu, Apr 12, 2012 at 10:24 AM, Prakash Singh <prakashbhu@gmail.com> wrote: > Friedrich, I am really sorry for this inconvenience and ignorance > > In continuation to my earlier question that the data set I am > referring contains item number in each level. with you proggraming > help what I could do was breaking the level data at item number wise > and them merging it back. > > Now, suppose that I want to do the same for two different level data > and then merge all the data created at item number basis at once. > > for example level3 data has item number from 309 to 319 so we get 10 > data at item number and merged it.
