Get only those data from Share point External content type depending on the logged in user.

Hi,

The throttle value of the list is 20000 that is defined by the company. But the data in the BCS list is increasing more than 20000 and the list is throwing an error as it not able to accommodate data more than 20000 records. 

I created Read list comparison filter for the logged in user name.  I referred the below link for the same:

I used the below query for the same:

But the above query is not fetching any result, I referred the below link for the query

Thanks and Regards,
