The date introduces the group. The total summarizes the group. You can see how grouping works by comparing the List of Products by Category report shown in the following illustration to the datasheet for its underlying query, Product List. Both the report and the query sort products by category, but the report also prints the name of each category on a separate line at the beginning of each group in the group header and the number of products for each category on a separate line at the end of each group in the group footer. The category name appears in every row in the datasheet. The category name appears once for each group in the report, in the group header. The total for the category appears at the end of each group, in the group footer. The records appear as one large group in the datasheet. The records for each category appear as a separate section in the report, preceded by a group header and followed by a group footer. You can group on any fields and expressions you sort on up to 1. You can group on the same field or expression more than once. This topic describes the common uses for Reporting Services report parameters, the properties you can set, and much more. Report parameters enable you to control. When you group on more than one field or expression, Office Access 2. The first field you group on is the first and most significant group level the second field you group on is the next group level and so on. The following illustration shows how Office Access 2. Each group header is paired with a group footer. You usually use a group header to display data that identifies the group in a separate section at the beginning of the group. Use the Report Wizard. You can also use the Report Wizard to create a report. The Report Wizard provides you with more flexibility than you get by using the Report. You usually use a group footer to summarize the data in the group in a separate section at the end of the group. Top of Page. About the report sections. In Access, the design of a report is divided into sections. To create useful reports, you need to understand how each section works. For instance, the section in which you choose to place a calculated control determines how Access calculates the results. The following list shows a summary of the section types and their uses. Report Header Printed once at the beginning of the report. Use the report header for information that might normally appear on a cover page, such as a logo, or a title and date. The report header prints before the page header. When you place a calculated control in the report header, the value is calculated for the entire report. For example, placing a control that uses the Sum aggregate function in the report header calculates the sum for the entire report. Page Header Printed at the top of every page. Use a page header, for example, to repeat the report title on every page. Group Header Printed at the beginning of each new group of records. Use the group header to print the group name. For example, in a report that is grouped by product, use the group header to print the product name. When you place a calculated control that uses the Sum aggregate function in the group header, the sum is for the current group. Detail Printed once for every row in the record source. The Detail section is where you place the controls that make up the main body of the report. Group Footer Printed at the end of each group of records. Use a group footer to print summary information for a group. Page Footer Printed at the end of every page. Use a page footer to print page numbers or per page information. Report Footer Printed once at the end of the report. Use the report footer to print report totals or other summary information for the entire report. Note In Design view, the report footer appears below the page footer. However, when the report is printed or previewed, the report footer appears above the page footer, just after the last group footer or detail line on the final page. Top of Page. About controls. Controls are objects that display data, perform actions, and let you view and work with information that enhances the user interface, such as labels and images. Access supports three types of controls bound, unbound, and calculated. The following list shows a summary of these controls and their uses. Bound control A control whose source of data is a field in a table or query. You use bound controls to display values from fields in your database. The values can be text, dates, numbers, YesNo values, pictures, or graphs. A text box is the most common type of bound control. For example, a text box in a form that displays an employees last name might get this information from the Last Name field in the Employees table. Unbound control A control that doesnt have a source of data. You use unbound controls to display information, lines, rectangles, and pictures. For example, a label that displays the title of a report is an unbound control. Calculated control A control whose source of data is an expression rather than a field. You specify the value that you want in the control by defining an expression as the source of data for the control. An expression is a combination of operators such as and, control names, field names, functions that return a single value, and constant values. For example, the following expression calculates the price of an item with a 2. Unit Price field by a constant value. Unit Price. 7. An expression can use data from a field in the reports underlying table or query, or from a control on the report. When you create a report, its probably most efficient to add and arrange all the bound controls first, especially if they make up the majority of the controls on the report. You can then add the unbound and calculated controls that complete the design by using the tools in the Controls group of the Design tab. You bind a control to a field by identifying the field from which the control gets its data. You can create a control that is bound to the selected field by dragging the field from the Field List pane to the report. The Field List pane displays the fields of the reports underlying table or query. To display the Field List pane, do one of the following On the Design tab, in the Tools group, click Add Existing Field. Press ALTF8. When you double click a field or drag it from the Field List pane to the report, you create a bound control. Alternatively, you can bind a field to a control by typing the field name in the control itself or in the box for the Control. Source value in the controls property sheet.
