CN41 — CN41 Project Structure Overview Report

CN41 belongs to the group of structure reports under the PS Information System, and it lists project definitions matching a selection variant, showing attributes such as status, dates, profile, plant, and responsible person in an ALV-style list. The single fact that explains most confusion around it is that CN41 is display-only: it reads master data, it never writes it. Consultants who expect to edit a status or a date directly from this list are in the wrong transaction; any change has to happen in CJ02 or the project builder. CN41 exists purely to filter, sort, and drill through a population of projects that would otherwise have to be checked one CJ03 call at a time, and its value is entirely in the selection screen and the drill-down, not in any update capability.

CN41 gets used when a consultant or project controller needs a filtered list of projects rather than a single project detail screen, for example during a portfolio review, a period-end audit of which projects are still open, or a check of every project under a given profile before a mass status change. It sits before, not instead of, the maintenance transactions: the typical sequence is CN41 to identify the population, then CJ02 or CJ20n to act on individual projects. On systems where a Fiori project overview app has been rolled out, that app tends to replace CN41 for ad hoc browsing, but CN41 remains the fallback when a specific selection variant or a legacy layout is required and nobody has built the equivalent app variant.

To confirm why CN41 returned an unexpected result, run SE16 on PROJ using the same selection criteria entered on the CN41 screen: project profile, status, and any organizational fields. Compare the row count to what CN41 displayed. If PROJ contains more rows than CN41 showed, the gap is almost always a status filter or an authorization restriction, not a data problem. Cross-check the missing project's status by reading its entries in JEST against the status values excluded on the CN41 selection screen.

CN41 continues to work on S/4HANA in SAP GUI unchanged; the underlying PROJ and PRPS reads have not been restructured for this report. Where an organization has adopted the newer project overview Fiori apps, those tend to cover the same ad hoc browsing need with better filtering and a modern UI, but they are not a strict one-to-one replacement of CN41's selection variant logic. Sites still running classic PS reporting continue to rely on CN41 without modification.

This is functional PS territory in essentially all cases; CN41 has no configuration or customization surface that would pull in ABAP or Basis, apart from generic ALV performance issues on very large selections. A clean handover states the exact selection variant used, the expected versus actual row count, and whether the discrepancy tracks to status, authorization, or date filtering.

CJ01, CJ02, and CJ03 are the create, change, and display transactions for WBS elements that a consultant moves to after identifying a project in CN41. CJ20n is the project builder, the interactive alternative for structural maintenance across the whole project hierarchy. CN22 sits in the same PS Information System structure reports family, covering a different object level, and is worth comparing against CN41 when the drill-down behavior or selection logic needs a second reference point.
