Add check in validateWrite method, calculate existing records and return false if there are already five records.

Do you still have some open question?

You wrote "I have three forms Book Trans, BookTable and student table. I want to insert five transactions in the BookTransaction form with the same student id(field in student table) and stop when it triggers the sixth time."

and

"I want to insert 5 record with one Studentid,more than that it should throw error.

And there are 4 student id"

It doesn't seem consistent.

If you have some question, please explain the process and expected outcome. Thanks!
