Warning
SAP does not support modifying a recurring instance. The only officially supported way of modifying a recurring instance is to recreate it.
How it Works
There are certain properties that can be modified on a recurring instance regardless of what format it is scheduled for. For example, the ownership, the start and end dates, and the number of retries can be changed without needing to worry about the type of object (It would even work on scheduled webi reports).
However, other properties can only be changed if the instance is scheduled to native crystal report format. For example, the database logon credentials or any destination option such the Unmanaged disk path or SMTP destination email. The reason these cannot be changed is because the SDK methods to do so are only available to the Crystal Report Plugin type.
To get around this, the sample tricks the Enterprise server into thinking that the instance is scheduled to native crystal report format by changing the SI_KIND property before modifying it, and changing it back afterwards.
Note: As mentioned above – this is not an officially supported workflow.
How to Use It
- Copy the code pasted at the bottom of this blog into a jsp page and copy that jsp page into the folder C:\Program Files (x86)\SAP BusinessObjects\tomcat\webapps\AdminTools
- Copy the following jar files from the folder:
C:\Program Files (x86)\SAP BusinessObjects\SAP BusinessObjects Enterprise XI 4.0\java\lib
to the folder
C:\Program Files (x86)\SAP BusinessObjects\tomcat\webapps\AdminTools\WEB-INF\lib
SL_plugins.jar
cereports.jar
CrystalReportsSDK.jar - This one isn't needed to run the sample - but copying the other two seems to break query builder unless you include this one.
- Restart Tomcat (Whenever you add a file to the lib directory you must restart the app server. Adding or modifying a jsp file as per step 1 does not require a restart)
- Edit the code and change the values in the following sections:
String reportQuery = "Select * FROM CI_INFOOBJECTS where (SI_INSTANCE=1 or SI_RECURRING = 1) and SI_SCHEDULEINFO.SI_PROGRESS = 1";
Change this query to return back the reports you want to modify. I recommend testing the query in query builder (http://myServer:8080/AdminTools) first.
On line 164 change the logfile path to the location you want the log file to be written to.
FSout = new FileOutputStream("C:\\Program Files (x86)\\SAP BusinessObjects\\tomcat\\webapps\\AdminTools\\TestOutput.txt", true);
Because this is java, all slashes must be double slashes.
// User Credentials
String username = "Administrator";
String password = "Password1";
String cmsname = "<myserver>";
String authType = "secEnterprise";
The logon credentials for the Enterprise server. It is recommended to use the Administrator user for this.
- Uncomment (remove the // in front) the calls to the functions you want to use.
// Update the database username and password.
//changeReportDBLogons(tmpReport, "myUsername", "myPassword");
// Change how many retries are allowed
//changeReportRetries(tmpReport, 5);
// Change the file IO username and password for unmanaged disk location
//changeReportUnmanagedDiskLogonCredentials(tmpReport, infoStore, "myOSUsername", "myOSPassword");
// Change the time the next instance will run at
//changeScheduleStartTime(tmpReport, new java.util.Date("7/13/25 4:15:00 PM"));
// Change the end time of the scheduled instance (The last time it will be allowed to run - defaults to 10 years in the future)
//changeScheduleEndTime(tmpReport, new java.util.Date("7/13/26 4:15:00 PM"));
// Change the from field for a schedule to SMTP instance
// changeScheduleFromFieldForScheduleSMTP(tmpReport, infoStore, "default@myserver.com");
There are 6 functions in this sample.
changeReportDBLogons – Change the report database username and password
changeReportRetries – Change how many retries to do
changeReportUnmanagedDiskLogonCredentials - If the report is scheduled to unmanaged disk – then you can change the OS logon credentials used
changeScheduleStartTime – Change the time the next instance will run
changeScheduleEndTime – Change the end time of the instance. That is – the last time it will be allowed to run. This defaults to 10 years in the future.
changeScheduleFromFieldForScheduleSMTP – If the report is scheduled to SMTP – then change the FROM field for the SMTP portion.
