i am not able to use Any type (data type) in Process model . what to do

use tointeger() or tostring() to convert 

Store it as text via a!tojson.

If you do not need this for something exotic, use maps.

Can you specify what you're trying to actually accomplish?  This question could have a thousand different potential actual answers...

i used Datasubset it worked

I suggest to not do it that way. Is there a specific reason to NOT use a map?

yes Actually i m querying big Query Data in Process model .. and i didnt wanted to use Record Type bcs data is huge so One time query i m doing on the fly>>

but anyways i ve used todatasubset() to convert BQ data  to use further in PM

Thanks Stefan ,yea we can use map too

Actually not particular reason  we are quering big query data on the basis of some conditions in PM so after getting data i am converting to datasubset .

so once i have data i can check some Conditions relevant to data stored in Our RDBMS().

I suggested to create a record type but our senior member told data is more than 7 million so its better to query in PM on the fly one time and utilise it 

so for that purpose i was doing 

You are aware that storing larger volumes of data in a process will risk your system stability?!?!?
