How to Implement PROC REPORT for Customized Reports in SAS

Introduction

For SAS professionals aiming to create highly customizable reports, PROC REPORT offers an ideal solution. PROC REPORT is a versatile procedure within SAS, allowing users to structure, format, and customize data reports to meet specific needs. This article dives into using PROC REPORT for generating tailored reports, exploring its syntax, options, and practical applications for SAS professionals seeking to elevate their reporting capabilities.

What is PROC REPORT?

PROC REPORT is a SAS procedure designed for generating reports with flexible layout options, enabling users to control every detail of the presentation. Unlike simpler procedures like PROC PRINT or PROC MEANS, PROC REPORT provides advanced features for grouping, ordering, formatting, and summarizing data, making it ideal for creating sophisticated, reader-friendly reports.

Why Use PROC REPORT for Custom Reporting?

PROC REPORT stands out for several reasons:

• Customizable Layout: Users can specify headers, arrange columns, and control cell formatting.
• Complex Grouping and Summarization: Summarize data by multiple levels and apply custom statistics.
• Flexibility in Data Presentation: From basic listings to complex cross-tabulations, PROC REPORT adapts to diverse reporting requirements.

PROC REPORT is ideal for detailed financial summaries, sales reports, and any scenario where polished, customized output is essential.

Basic Syntax of PROC REPORT

To use PROC REPORT effectively, understanding the basic syntax is essential:

PROC REPORT DATA=dataset_name;
    COLUMN variables;
    DEFINE variable / DISPLAY | GROUP | ACROSS | ANALYSIS;
RUN;

• COLUMN: Lists the variables to be included in the report.
• DEFINE: Specifies how each variable should be displayed in the report, with options like DISPLAY, GROUP, ACROSS, and ANALYSIS controlling how data is handled.

Example: Creating a Simple PROC REPORT

Suppose we have a dataset called sales_data with variables region, product_type, and sales_amount. A simple PROC REPORT setup might look like this:

PROC REPORT DATA=sales_data;
    COLUMN region product_type sales_amount;
    DEFINE region / GROUP;
    DEFINE product_type / GROUP;
    DEFINE sales_amount / ANALYSIS SUM;
RUN;

This example generates a report that summarizes sales_amount by region and product_type, calculating the sum of sales_amount for each group.

Key Options in PROC REPORT

PROC REPORT offers various options for customizing reports, from layout controls to statistical summaries.

1. GROUP and ACROSS Options

• GROUP: Used in the DEFINE statement, the GROUP option groups data by specified categories.
• ACROSS: Creates columns for each level of the specified variable, enabling cross-tabulation.

PROC REPORT DATA=sales_data;
    COLUMN region product_type, sales_amount;
    DEFINE region / GROUP;
    DEFINE product_type / ACROSS;
    DEFINE sales_amount / SUM;
RUN;

In this example, product_type becomes a column header for each product type, with sales amounts summarized beneath each header.

2. ORDER and DISPLAY Options

The ORDER option in PROC REPORT allows you to order rows based on a variable, while DISPLAY simply displays the data without grouping or summarizing.

PROC REPORT DATA=sales_data;
    COLUMN region product_type sales_amount;
    DEFINE region / ORDER;
    DEFINE product_type / DISPLAY;
RUN;

Formatting Data in PROC REPORT

PROC REPORT supports extensive formatting options to control how data appears in the output.

Adding Labels

To apply meaningful labels to variables, use the LABEL option within the DEFINE statement.

DEFINE sales_amount / ANALYSIS SUM "Total Sales";

Formatting Numeric Values

Formats can also be applied to numeric variables to enhance readability:

DEFINE sales_amount / FORMAT=dollar12.2;

This example formats sales_amount as a dollar value with two decimal places.

Applying Statistical Summaries in PROC REPORT

PROC REPORT can generate summary statistics like totals, means, and counts. Using the ANALYSIS option, you can specify various statistics for numeric variables.

PROC REPORT DATA=sales_data;
    COLUMN region product_type sales_amount;
    DEFINE region / GROUP;
    DEFINE product_type / GROUP;
    DEFINE sales_amount / ANALYSIS SUM MEAN;
RUN;

Here, PROC REPORT calculates the total and average of sales_amount by region and product_type.

Customizing the Layout of PROC REPORT

Using COMPUTE Blocks for Dynamic Content

COMPUTE blocks enable you to create custom cells, add conditional formatting, or apply calculations in the report.

PROC REPORT DATA=sales_data;
    COLUMN region product_type sales_amount;
    DEFINE region / GROUP;
    DEFINE product_type / GROUP;
    DEFINE sales_amount / ANALYSIS SUM;
    COMPUTE sales_amount;
        IF sales_amount.SUM > 50000 THEN CALL DEFINE(_ROW_, "STYLE", "background=lightyellow");
    ENDCOMP;
RUN;

In this example, if the total sales_amount exceeds 50,000, the background color changes, helping highlight significant values.

Specifying Titles and Footnotes

Titles and footnotes are essential for providing context to reports, especially for complex data summaries.

TITLE "Quarterly Sales Report";
FOOTNOTE "Generated on &sysdate.";

Practical Applications of PROC REPORT

1. Creating Financial Reports

PROC REPORT is often used for detailed financial reports, summarizing revenues, expenses, or other financial data by department, region, or product.

2. Generating Sales Analysis

For sales reports, PROC REPORT can summarize data by product categories, regions, or time periods, enabling in-depth trend analysis.

3. Employee Performance Reports

Human resources professionals can use PROC REPORT to summarize employee performance data, using grouping and statistical summaries for metrics like sales, productivity, or attendance.

Integrating PROC REPORT with Other Procedures

PROC REPORT can be combined with other SAS procedures like PROC FORMAT to create custom formats and enhance report readability.

PROC FORMAT;
    VALUE sales_fmt
        low-50000 = 'Low'
        50000-100000 = 'Medium'
        high-100000 = 'High';
RUN;

PROC REPORT DATA=sales_data;
    COLUMN region product_type sales_amount;
    DEFINE region / GROUP;
    DEFINE product_type / GROUP;
    DEFINE sales_amount / FORMAT=sales_fmt.;
RUN;
