input value must not exist already in odata

[Former Member]

How can I validate the Input of a field for creating new data, comparing with duplikates already existing in odata?

I don't know how to handle the Information from odata model to compare values.

Many thanks

Do you want to compare the user entered data with the data from backend?

If yes, then trigger the service and store the data from backend service into a local json model.

Then, compare the user data(input field) with the data in local json model.

If your scenario is completely different, then ignore the above lines. 😞
