Prevent Estimation run by Division

Hi all,

How do I prevent estimation from running (tx code EL18) for a particular division? In the configuration SAP Utilities -> Device Management -> Meter Reading -> Meter Reading Result -> Estimate, I did not make the entry for that particular division, but still EL18 is running the estimation for that division (note I am using same MRU but for different division).

Thanks for your help.
