IW29 — Display PM Notifications List

IW29 is the list display transaction for PM and CS notifications: malfunction reports, activity reports, and maintenance requests. It presents a multi-field selection screen and returns results as an ALV list, strictly read-only. The structural fact that causes most confusion is that IW29 and IW28 share the same selection screen and near-identical list layout; the only real difference is that IW28 permits mass changes from the list and IW29 does not. A second source of confusion is the default status radio button on the selection screen, which frequently restricts the result to outstanding notifications only, so completed or closed items appear to be missing when they are simply filtered out.

IW29 is reached for during reporting and monitoring activity rather than processing: shift handover reviews, weekly backlog checks, KPI extracts, pre-shutdown status reviews, or ad hoc checks of what has been reported against a functional location or equipment. It is preferred over IW28 whenever the user should not be able to accidentally change a notification, and it is often the transaction handed to plant supervisors or reliability engineers who need visibility but not edit rights. In S/4HANA environments with embedded analytics, a Fiori list app covering the same notification data is the equivalent entry point for users working outside the SAP GUI.

Pull QMEL filtered by plant (IWERK), notification type (QMART), and date range to reproduce the selection the user ran. Take the object number (OBJNR, built from the notification number) and look it up in JEST joined to TJ30T to see the actual current status text; this explains why a notification the user expects to see is excluded under an 'outstanding' filter. Cross-check IHPA for the person responsible filter, since a mismatch there silently drops rows without any error message.

IW29 exists unchanged in S/4HANA and continues to run against the same notification tables; the underlying selection logic and status model were not restructured. The list output uses the standard SAP list viewer as before. For users working in Fiori-first setups, a maintenance notification list app provides equivalent filtering with a more modern interface and easier mass export, but it does not replace IW29 in the GUI-based support workflow.

This is a functional PM or CS issue in almost every case: selection scope, status filters, and authorization for notification types belong to the plant maintenance or customer service configuration owner. ABAP involvement is limited to custom selection-screen fields or enhanced list layouts. A good handover includes the exact selection variant used, the status radio button setting, and the notification number expected to appear but missing.

IW28 is the direct companion transaction, adding mass-change capability to the same selection logic, and is the natural next read for anyone who needs to act on the list rather than just view it. IW21, IW22, and IW23 cover single-notification create, change, and display, useful for understanding what generates the rows IW29 reports on. IW38 and IW39 are the order-level equivalents and are worth comparing when a notification and its linked order disagree on status. IH01 gives the functional location hierarchy context behind the location and equipment filters used on the IW29 selection screen.
