Hello
The alter statement shows there is a space in between data and 24.
What makes me wonder is how come you have kbp_24 twice under sapdata4.
I see there are two datafiles of kbp.data24
What I will do is first rename the datafile /oracle/KBP/sapdata4/kbp_24/kbp.data24 (the one without space) to a different name (if possible to a different location).
Once this is done I will check whether the database is using the renamed file.
Then follow the procedure give by Michael.
If you go to support there is a strong possibility they will reject support as you didn't use BRTools.
Regards
RB
