mCreate One table and allow multi-Environment to read and delete data

I hope someone can show where is the issue.  My objective is to create ONE table and then allow mulit- environment to read from and delete data in this table.

I was told to

1) Create the table ( OneTable ) into an Environment ( called DEVALL ). 

2) Use Object Configuration Manager to map this OneTable from DEVALL to all other environment ( eg.  ENV1, ENV2 )

3) make sure it is in Active status

That it

But then I create a UBE ( run in ENV1  in fat client ) and insert data into this OneTable, it keeps return error.    

am I missing any step?  Is it because I run the UBE in fat client
