The exam is delivered as multiple-choice questions covering the eight planning domains, from fundamentals and the planning hierarchy through BOM explosion, netting and lot sizing, capacity planning, exception management, and ERP performance metrics. The certifying body publishes the current delivery method, item count, and time allowance; check its official site before you schedule.

Candidates with hands-on planning experience usually find the conceptual questions straightforward and the calculation questions demanding. The difficulty lies in time-phased arithmetic: projected available balance, net requirements, planned order releases offset by lead time, and lot-sizing comparisons. If you can work those by hand without a spreadsheet, the exam feels manageable.

Retake rules, waiting periods, and any fees are set by the certifying organization and can change. The official site is the only reliable source for current retake policy. Before rebooking, identify which domain cost you the most marks and rebuild that area rather than repeating general review.

Most candidates need several weeks of focused study, not several days. Work through one domain at a time, do the calculations by hand, then revisit the weakest areas. If you already plan in an ERP system daily, you can compress the conceptual review and spend most of your time on lot sizing, capacity, and exception logic.

Follow the planning flow: hierarchy and fundamentals, then MPS and demand management, then BOM structure and explosion, then item master and lead-time data, then netting and lot sizing, then capacity planning, then action messages and exceptions, and finally ERP integration and metrics. Each domain depends on the ones before it, so this order minimizes backtracking.

Three recur. First, confusing gross and net requirements, or forgetting to net on-hand and scheduled receipts. Second, offsetting a planned order in the wrong direction when applying lead time. Third, treating a system action message as an instruction rather than a signal to investigate. A fourth is weak BOM literacy - misreading levels, phantom items, or low-level coding.

Both, but formulas matter more than candidates expect. You should be able to compute projected available balance period by period, derive net requirements, compare lot-sizing rules such as lot-for-lot and fixed order quantity, and calculate load against available capacity. Conceptual understanding alone will not carry the calculation questions.

No. The exam tests planning logic that applies across ERP systems, so terminology and calculation methods are vendor-neutral. Screens differ between products, but the underlying netting, explosion, and offsetting logic does not. Learn the principles and you can map them onto whichever system you use at work.

The passing standard is set by the certifying body, which publishes the current scoring method and passing score on its official site. Do not rely on figures quoted in forums or older study material. Aim to be comfortably above any threshold by targeting consistent accuracy across all domains rather than excelling in a few.
