We can see the size is 30 on PPM for Detail of Benefit Plan Detail but the DB size is 240.
Then you can input 80 characters.
If you use XOG then the input check does not work so that you can input the characters over than 30.
And you can see the characters over than 30 but if you change the value and save it then
you have the error.
You need to define this within 30 characters on PPM UI and this value is not allowed to be duplicate so that please define this within 30 characters and unique value.
Unless you define then it is possible that it may affect system.
