You can combine conditions to increase control over the data a report contains. Combining conditions lets you retrieve data that, for example, contains the people Smith or Johnson, or concerns female clients. Whenever you have more than one condition in a report, Yellowfin automatically combines them with an And. All you have to do to combine conditions is add them to your filter list.

Between each filter there is an AND / OR drop down option the user can define. This allows the user to define how the combination of multiple filters should work together to return results.

And / Or

Logical operators let you specify how you want conditions combined. Yellowfin filters allow two types of logical operators:

1. The AND logical operator combines two conditions into a narrower condition. A data item must meet the first condition and the second condition to meet the condition's requirements.
2. The OR logical operator combines two conditions into a broader condition. A data item can meet the first condition or the second condition to meet the condition's requirements. For example return clients where their last name = Smith or their Gender = Female.

To adjust the logic, simply select And or Or from the drop down list between the pair of filters. When changing the logic you may need to use sets of brackets in order to contain items. To do this, simply click on the > arrow next to the pair of fields you wish to put in brackets. To remove, click the < arrow

If you've combined at least three conditions in your query, you can bracket certain conditions to bind them together. You use this the same way you might use parentheses to change the value a in the following arithmetic equations:

a = 36 * (6 +12) as opposed to a = (36 * 6) + 12

For example, you want information about the Events or People in the system on a particular day.

1. To create a bracket, select the line that you wish to bracket and click the bracket icons (initially the right pointing arrow). This will indent the line and create the bracket condition. To view the result of the bracket read the statement in the filter logic section below the filter attributes table.
2. To change the level of the bracket you can use the move up and move down links to change the order of your filter attributes in the statement.

Example

If you want to return all the records you have that have and Active Booking Status AND have either a Booking Method of Web Site OR Media Category of WebView the following would be defined:
