Listing problem in IS Retail

hi

need help regarding listing in IS Retail.

for one article in MM43 under listing tab, if i click on assorts, system shows one site say 1000. but if i go to MM60 list, it shows all the other sites also like 1001, 1002, 1003 etc.. how is it possible? MM60 shows that the article has been listed for 1001, 1002 & 1003 also while in article master it shows only 1000.

thanks & regards'
