Need your advice on this, as per this note 1231922.1
In this note they mentioned a solvtruncation.sql script to
Manually insert the colums after the character set migration.
is it possible to be done for the application tables.
Deleting the rows affected in truncation before chaging it into AL32UTF8, then inserting those data's back into the table after converting the characterset.
is it possible for the application tables.
I would say it's possible, however I would suggest you log a SR and confirm it with Oracle support.
You may try it in your test instance and see if it works.
Thank you so much Hussein and Yes we are logging a new SR with the EBS team.
