Lab project — Design and distribute a library of professional reports, from connection to distribution
- Objective: build a set of reports useful to an organization from a data source — a formatted list, a grouped report with subtotals, a fixed-format document (invoice/statement), an analytical report (cross-tab, chart, Top N), all parameterized (interactive), accurate (verified joins), performant (server-side) and distributed (PDF/Excel export).
- Material: the Crystal Reports cheat sheet below (sections, joins, formulas, performance, best practices) to keep at hand.
- Method: one step per level. You connect and get to grips with the environment, create a first report, enrich it (sort, grouping, totals, filters, parameters), add the power of formulas and conditional formatting, then the expert functions (subreports, charts, cross-tabs), and finally you distribute (export, integration) while taking care of performance and accuracy.

Step 0 · Level 0 — Getting started & connection (N0)
Install the designer (free trial), understand the logic of SECTIONS (where/how many times), connect to a source and LINK the tables (joins — crucial step).
Step 1 · Level 1 — First report (N1)
Create a report with the wizard: choose the right tables, place the fields in the sections (data → Details), format (number/date format), add a title, special fields ("Page N of M") and check the preview.
Step 2 · Level 2 — Organize, filter, parameterize (N2)
Sort and GROUP (by customer/month), add SUBTOTALS (Group Footer) and a grand total, filter SERVER-SIDE, make the report interactive with PARAMETERS, and master the sections (summary/detail, pagination).
Step 3 · Level 3 — Formulas & conditional formatting (N3)
Create FORMULAS (calculations, categories via If/Select), apply CONDITIONAL FORMATTING (negatives in red, thresholds), add running totals (running balance) and advanced groups (Top N, sort by group).
Step 4 · Level 4 — Expert functions (N4)
Add a SUBREPORT (related/multi-source data — at a group level for performance), a CHART (right type), a CROSS-TAB (dimension with few values in columns); use an SQL command if needed, alerts/drill-down.
Step 5 · Level 5 — Distribute & make reliable (N5)
EXPORT in the right format (PDF to read, Excel "data only" to analyze), add DYNAMIC/cascading parameters, consider application integration, and above all OPTIMIZE (server-side) and VERIFY accuracy (joins, cross-checked totals) before distributing.
Success criteria
- Real hands-on: environment installed, SECTIONS logic understood, source connected and tables correctly LINKED (joins) — the data foundation.
- Structured and interactive reports: a grouped report with SUBTOTALS (at the right level) and a grand total, filtered SERVER-SIDE, made REUSABLE with PARAMETERS, with clean number/date formatting and mastered pagination.
- Analytical power: FORMULAS (calculations, If/Select categories), CONDITIONAL FORMATTING (flag key values), and at least one expert report (multi-source subreport, chart, cross-tab, or Top N).
- Professional and reliable distribution: reports EXPORTED in the right format according to use (PDF/Excel), OPTIMIZED (server-side filtering, minimal volume) and above all ACCURATE (verified joins, totals cross-checked against known values, handled nulls), tested on real data — the complete cycle, from connection to accurate, clear and distributed reports.
