This course shows business analysts how to use SAP Crystal Reports 2011 to analyze and summarize data to make better decisions. Author Curt Frye teaches how to maximize the power of Crystal Reports and import and analyze data from a variety of places, including Excel, Access, HTML/XML files, and more. The course also shows you how to define and manage reports, summarize data, visualize data using charts, focus analysis by selecting which data a report summarizes, export report data, and connect to external data sources.
Filtering the records in a report using a Parameter field lets you focus on the data that is most important to you. So far in this chapter I have shown you how to define a single-value Parameter field. In this movie I will show you how to define Parameter fields that let you select multiple values at the same time. This report contains an existing Parameter field called Quarter. It is over here in the Field Explorer. If you do not see the Field Explorer, you can go up to the standard toolbar and click the Field Explorer button to display it. As currently configured, the Parameter field only allows a single value, so I want to go in and change it.
If you need to review how to create a Parameter field you can go back to the first movie in this chapter. But for now, I will click Quarter, which is the Parameter field, and then click the Edit button. Just too quickly look at what the Parameter field is, it's named Quarter and is of Type Number--in other words, it contains numeric values--and it is a static list which I entered here in the Value list. So now what I want to do is allow multiple selections at the same time.
To do that, I will go in to the Value Options area and scroll down and here it says Allow multiple values. I will click over on the side of the line where it says False. This displays a list, and I am going to change that property's setting to True and then click OK. So now when they enter Values Dialog Box appears, like it did in previous movies, we can select multiple values. So if I wanted to see only the data for quarters 2 and 3, I could click 2 and then click the Add button. And then the highlight moved down to 3 automatically, so I will click Add, so we have 2 and 3.
If I wanted to remove one of those values, I could select it and click Remove or to remove all of them, I could click All. But I do want to look at 2 and 3, have that as my filter, so I can click OK. And when I do, data for Quarters 2 and 3 appear inside the body of the report. If Crystal Reports displays a dialog box asking you either to identify the data source or to make a connection, then you can connect to the call data file using the techniques that you've learned elsewhere in this course.
Letting users select multiple values in a Parameter field gives them the power to display just the data they are interested in. Rather than go into one value at a time and try to keep the numbers in their head when they change the Parameter value, multiple values puts all of the data in the report at one time.
