Hello Noemi,
It looks like a authorization problem. Error code -24950
-24950: ERR_USRFAIL - user authorization failed
Explanation
The authorization on the DBM server failed. The user name and/or the password used are not correct.
User Response
Enter the correct user/password combination and log on to the DBM server again. You can correct the user data for the database instance in the Database Manager GUI.
Here's my next recommendation:
Enter transaction DB59 -> Select MaxDB Instance and run a connection test to see if the users are correctly setup. If the tests fail with user authorization error, go to DB59 -> Integration data and update the user/password of DB Users and save. Do the connection test again.
If this is not the case, then please goahead and create a SAP ticket on component BC-DB-SDB - Our support team has to check the issue directly on the affected system.
Regards,
Yashwanth
