Hi Andie,
Since in your procedure, you're setting both texts as 'P' (changes column), all information you entered in your business transaction text will disappear after SAVE and will be stored in a text defined as 'R' (changes column). You're missing this text type in your procedure.
Or, just remove the 'P' definition if you want to keep the changes in your text type.
See if it helps you a little more!
Kind regards,
Garcia
