Hi There, I have a lookup table that generate one lookup table yet it has some custom column that do not have values by default, and I add custom values to them. The columns which I want to update by SPL are host index firstTime lastTime totalCount The columns which I want to update their values manually are: accepted_delta is_expected Below is a screenshot of this table. Currently we are using the following daily SPL to update this table, but I am really bad at SPL, the bug is that it will just overwrite everything that in this lookup table and all my custom values (columns of accepted_delta, is_expected) all gone. | tstats count as totalCount earliest(_time) as firstTime latest(_time) as lastTime where index!="main" by index host | fields host index firstTime lastTime totalCount accepted_delta is_expected | fillnull value=1000000000 accepted_delta | fillnull value="false" is_expected | outputlookup nonforwarderhost.csv
