Give me some suggestion for this below case( Data transform )

Currently User can submit two same event reasons in same NPLR case (also on same day). But this should not be allowed.

User can add 2 same event reasons but it should have different create date.

@VenkadeshM16673202 can you trigger a DT on change of the “Reason for Adding” and use IndexInPagelist to identify if the value already exists in other page. If it exists, then get the index and compare the dates as well. If they match you can add an error message

@kammv , If suppose we are using issue through Validation means, how shall we implement in validation?

@VenkadeshM16673202 If you want to use a validate rule, try this function “CheckDuplicatesInPageList”. We need to compare both the value in dropdown and the date

Here is an article with the syntax to refer to the function

@kammv ok Thank you so much! I’ll refer and I’ll do.
