Missing System Generated Behavior after condition was set

[ZoroK]

Hi all, i need some helps here.

I am giving condition (Yes/No) to a system generated behavior "Add" to add a reference row to other table.

now()<[Invoice No.].[Created Date Time]+"001:00:00"

but the "Add" button is missing even the condition is true.

I tried giving other condition like useremail(), it works perfectly, the button show up as it should. Any advise on solving this? or is it a bug? Thank you.

Add is NOT a row based action. therefore column values are not available.

So the system cannot know what[Invoice no.] points to..

Thank you TeeSee1, so the solution is I set validation on a specific column when users try to add in a new row, instead of the "Add" button.

Correct.

If you need a user input to judge whether to allow to add a row or not, then you have to at least give the chance to try to add one.

Then based on the user input, you can inform the user if their input is valid or not.
