Bex Analyzer - error msg 'Namespace /BIC/ must be se to chg.' - ho to grant auth. to change queries only to specific users

Hi to all,

a user is trying to save a query with Bex analyzer and receives error msg :  R7 063 Namespace /BIC/ must be set to changeable (transaction SE06).

I tried to look into SE06, and guessed that , changing the attributes of parameter /BIC/ from not modifiable to modifiable, will probably allow the user to change/save queries. Is my guess correct?

My worry is that changing such a parameter , will then allow each and every user to change/save queries.

How can I manage the possibility to change/save query via authorizations? Which role/auth. object can I set up in order to achieve my goal?

Thanks and regards,Carlo
