The job failed. Unable to determine if the owner (Domain\User) of job SSISJob has server access...

I created a SSIS package, which connects to the SQL Server database using windows authentication.
Package run successfully when I executed it in the BIDS and I tried to schedule a job to execute the package.

When I tried to run the job, I got the below error message.

The job failed.  Unable to determine if the owner (Domain\User) of job SSISJob has server access (reason: Could not obtain information about Windows NT group/user 'Domain\User', error code 0x5. [SQLSTATE 42000] (Error 15404))

To fix it what I had to do is set the Log On account of the SQL Server Agent to a domain account.
Normally it is set for a built in account.
Then check whether the Owner of the job is set to the same domain user as the Log On account.

This fixed my problem and I was able to run the job successfully. 

Tips to avoid empty pages and white spaces in SSRS reports...

Sometimes we find that there are white spaces or empty pages in the SSRS report viewer output or the PDF output. In this post I am going to mention the tips we can use to avoid those.

• Set the ConsumeContainerWhitespace property of the report to True.
• Set the body content to fit enough for the Report Page Width. Consider the margins too. Body width + Left and Right margins needs to be less than the report page width. Otherwise there will be blank spaces while exporting to PDF.
• Remove unwanted space between the tables or charts in the report.
• Check the page breaks, and disable those if there are no data by checking the Count of the data set.
• Set the page breaks if you are setting the visibility of a particular section by using a parameter, by applying the same condition for the Disable property.

If those things were done properly, there will not be any unwanted white spaces or empty pages in the report.
