I am trying to add HISTID to my data extract and even though I select the variable it doesn’t get added.
The variable count in the data cart does not include pre-selected variables, such as HISTID. Also note that HISTID is an individual-level variable, and will only be added to your extract if you select at least one individual-level variable.
Hi! Thank you for taking time to reply. I have downloaded an extract with individual-level variables and the HISTID variable hasn’t shown up.
Nevermind! My extract didn’t include an individual-level variable and now I have HISTID. Thank you!
I am glad to hear you were able to get HISTID in your extract. Our extract system requires users to include at least one non-pre-selected person-level variable to include persons in an extract.
