1215804 - OLAP reports sends blank password to database when refreshed in Crystal Reports


  • Login with no password sent to the database.
  • Database monitoring tool shows login errors.
  • If a lockout policy is set up on the database, passing the blank password after three attempts locks out the report from the database.
  • When refreshing an OLAP report in Crystal Reports, a blank password is passed to the database before the logon screen appears.
  • How to avoid sending empty logon to the database, when refreshing an OLAP report in Crystal Reports?


  • SAP Crystal Reports 2013
  • SAP Crystal Reports 2016
  • SAP Crystal Reports 2020

Reproducing the Issue

  1. In Crystal Reports, create a report off any data sources using an OLAP connection.
  2. On your database side, monitor the database logons.
  3. In Crystal Reports, refresh the report.
  4. On the database side, notice a logon error for an attempt to login with the user name you used to create the report, with an empty password. Why is this occuring?


  • Crystal Reports does not store the database password in a report, but does store the user name used to create the report. And by design, when refreshing a report in Crystal Reports, it always send a logon to the database with an empty password. If it fails, it then prompts for the user name and password to use to connect to the data source.


  • To change the behavior, and avoid sending an empty password when refreshing an OLAP report in Crystal Reports, add the registry key: AlwaysAttemptOlapLogon, and set the value to No     
    The following resolution involves editing the Microsoft Registry. Using the Microsoft Registry Editor incorrectly can cause serious problems. Use the Microsoft Registry Editor at your own risk. For more information, see the SAP Knowledge Base Article 1323322
