I have a requirement in one of the record producer, application/service variable is reference to bso

[Archana23]

I have a requirement in one of the record producer, application/service variable is reference to bso action table,if selected application is having the description in bso action table, it will auto populate in the description field in the form working as expected.

If application is not having any description and we have entered the test, if I change the application to other which was having the description the text which I entered is getting cleared and auto populating the description from the bso action table - working fine

If I change my mind and selected the application which was not having any description in the bso action table, the test which I entered should not get cleared. Is there any way to not to get cleared it.

Note: Not to use the hidden variable

Please suggest.
