Hello,
I’ve Got an Issue here.
I want to have sales input leads to my apps, and also recheck the duplicate phone number
but the problem is, when i set row owner on each sales’s input, it doesnt detect the duplicat
how do i solve it ?
Create a second list for phone numbers and users’ rows ID that has no row owner… if you keep your data in Google Sheets… then there is no problem at all, run a function there.
second list ?
what does it mean ? another table ?
i only use glide table, since gsheet consume too much sync update
Yes, another table…
GS consumes precisely the same amount of updates as GT…
and some cases even less 
another table did you mean, whenever an input occured, they need to input it to another table also ?
or can we created a computed column/relation to this new table , and then we create another relation to check duplicate?
sorry,
because my last app was using gsheet, and it consumes twice, table update and sync update between GS 
thats why i want to solely/only used glide table. hehe
correct me again if im wrong
My apps do not consume any updates…
Yes… when your users input new data… add a record to the separate table… they don’t need to input it twice… just action after submitting.
i already had 7000 record before, do i have to create another table with 7000 row also ?
or can it just 1 row, but an array of it ?
Yes, 1 row, with two arrays… one for user ID, one for Numbers… each time append a new value to the array… and check for duplicates
im sorry, what does User ID here does ?
If you want to track whom the number belongs to (optional)
how to add a record to separate table , when im inputting new data in Table1, but need to create a new action (set a column value) to another table ?
created relation, but it doesnt make it to there.
Why?
