Article Listing Fix

Dear Gurus,

We have created a single assortment ( Ex. C1000) for multiple sites, Ex site 1000, 1100, 1200, 1300 & 1500.

Now when we execute the listing in Article Master's Listing View, the article gets extended to the sites 1000, 1100, 1200, 1300 & 1500.

Now this is a standard behavior, Is there a possibility for us to restrict the extension of article to sites 1100, 1200, 1300 & 1500 but perform listing operation for an article in the site 1000 alone using the Listing View - execute Listing operation ? ( As we want to list the article only in the site 1000)

we can use wsm3 Transaction instead of Listing View Operation ( Do not want consider this as an option as it calls for Process change ).

Awaiting your replies !

Thank you in advance !
