Overview
Master SmartForms with driver programs, generated function modules, form interface, tables, pages, windows, conditions, output determination and real print debugging.
Lessons in this topic
- Smart Forms Part 1: What Smart Forms Are and How Printing WorksUnderstand SAP Smart Forms: transaction SMARTFORMS, the generated function module, the driver (print) program, form interface, pages and windows, Smart Styles, output control, and how Smart Forms compare with SAPscript and Adobe Forms.
- Smart Forms Part 2: Anatomy of a Smart Form and the Driver ProgramBuild a complete driver program for a Smart Form: selection screen, data retrieval into interface structures, SSF_FUNCTION_MODULE_NAME, control parameters (preview, no dialog, getotf), output options, printing multiple documents in one spool with SSF_OPEN/SSF_CLOSE, and checking job output info.
- Smart Forms Part 3: Output Determination and the Print Program EntryConnect a Smart Form to SD/MM output control: output types in NACE, processing routines (program, FORM ENTRY, form name in TNAPR), condition records, NAST fields in the driver, return codes, reprocessing with VF31/RSNAST00, and debugging output issues.
- Smart Forms Part 4: Form Interface — Import Parameters, Tables and Global DataDesign the Smart Form interface: DDIC types for import parameters and tables, global definitions (data, types, field symbols), initialization code, form routines, and why a clean data contract between driver and form matters.
- Smart Forms Part 5: Pages, Windows and Main Window FlowControl the physical layout of Smart Forms: pages and next-page sequence, main window vs secondary windows, final windows, page breaks, page-dependent content (first page vs next pages), page numbering with SFSY fields, and common layout problems.
- Smart Forms Part 6: Tables, Templates, Loops and ConditionsChoose the right node for structured output: table nodes for dynamic item lists with header/main area/footer, templates for fixed grids, loops, line types and cell layout, sorting and events (subtotals), calculations, and conditions on nodes.
- Smart Forms Part 7: Texts, Translations and Language HandlingHandle texts in Smart Forms: text elements, text modules (SMARTFORMS), include texts from SO10 and document texts (READ_TEXT objects like VBBK), translation with SE63, language selection via CONTROL_PARAMETERS-LANGU and NAST-SPRAS, and formatting with Smart Styles.
- Smart Forms Part 8: Debugging Smart Forms and Generated Function ModulesDebug Smart Form problems systematically: driver vs form, finding the generated function module, breakpoints in program lines and initialization, output control errors, missing or wrong data, layout issues, spool and PDF checks, and CONVERT_OTF for PDF output.
