member management not working as expected

Hi,we are trying to add new loc dimension member.

1. created member in worksheet, ex: site

2. in MM tool, it shows in member list, associated to default org .

3. when we want to link new site to some existing org, not able to do that.

we selected members from loc and item dimension, on create combinations or insert units, its not doing any thing.

later i queried mdp/sd, no records created.

on processing no errors pop up.

how to debug the issue???

any log for 

thanks
