Shop-on-behalf issue

Hi,

We are facing one issue where not all the users are shown in the shop-on-behalf search from the same company node.

For ex: If we have 50 users under the company node in PPOMA_BBP, and if a user tries to shop on behalf of these, then only few users are shown and some users are not shown in the shop-on-behalf search. System says "No values for this selection" for these users.

The user, who is trying to shop-on-behalf, has been assigned the correct id in his "Requester" attribute so no issues from that angle.

Any pointers in this regard would be helpful.

Thanks.
