when we try to change the sql query under edit command on a report, it does not allow to make changes and throws.error: Invalid Argument Provided. Details: The alias requested 'Command', contains a combination of characters which is not considered to be valid.
Reproducing the Issue
1- Create a new report
2- Click 'add command' and enter an SQL query.
3- Click OK to add the command to the Selected Tables list
4- Right click the newly added command and click Edit
5- Click OK --it is not necessary to change the SQL to cause the error .
6- Error message:Invalid Argument Provided.
Details: The alias requested 'Command', contains a combination of
characters which is not considered to be valid.
It is not practical to delete the command and add another since that will delete all fields from the report.
