The quick answer
Open Advanced Manufacturing > Manufacturing Reports > Downtime Graph - Category, set Date to All and read the tallest bars. Open Downtime Graph - Reason and pick a Downtime Category to see the reasons inside it. The bars carry no numbers, so confirm exact minutes in Downtime Report - Detail with the same period and filters.
The screenshots show sample data. Company, person, work order, item and work center names are fictional. The bar order, axis scale, label clipping and totals described here were observed in one account, so check them against your own release, role and configuration.
Before you start
You need Advanced Manufacturing, a role that can run its reports, and saved downtime entries on Advanced Manufacturing > Data Collection > Enter Results/Loss/Downtime/Labor. Downtime categories must exist, with each downtime reason set up under a category. In the account reviewed, each bar added up the duration, in minutes, of the events returned for one category or reason after the filters. The graphs do not draw anything for downtime that has not been saved. Category and reason names are configuration data and differ by account. Events whose reason has no category were not tested, so do not assume they appear. This example uses 21 downtime events with sample dates between 09/08/2026 and 10/12/2026.
01. Rank the categories
Go to Advanced Manufacturing > Manufacturing Reports > Downtime Graph - Category. In the reviewed account the page opened on its results with Date set to this month to date, here 10/01/2026 to 10/14/2026, and one bar: the single Breakdown event in the month, on an axis scaled from 0 to 21 minutes.
One bar says little, so open the Date field and choose All under Favorites. The From and To dates clear. Six bars appear, tallest first: Changeover, Breakdown, Material, Quality Hold, Admin and Scheduled Maintenance. The vertical axis is in minutes and the bars carry no numbers. Total at the top right counts the bars, not the minutes, so it reads 6.
02. Rank the reasons
Go to Advanced Manufacturing > Manufacturing Reports > Downtime Graph - Reason and choose All in Date. Twelve bars appear, one for each reason, and Total reads 12. Standard Changeover, a Changeover reason, is the tallest, and Motor Failure is second. Long names are cut off at the edge of the chart image, so use the Detail report for full names.
03. Narrow to one category
Breakdown was the second category, so open the Downtime Category filter and choose Breakdown. Five reasons remain: Motor Failure, Sensor Fault, Belt Slip, Hydraulic Leak and Jam. In this sample Motor Failure is more than half of the category's minutes. Each reason in the sample is set up under one category, so with the same period and filters the five bars add up to the Breakdown bar on the Category graph. That does not hold for events with a missing reason or category, which were not tested.
04. Confirm the exact minutes
Go to Advanced Manufacturing > Manufacturing Reports > Downtime Report - Detail, choose All in Downtime Start and Breakdown in Downtime Category. All is the same period the graphs used, and no other filter is set. Eight events are listed and the Total row reads 204 minutes, the sum of the five reason bars in this sample. If you used a bounded period on the graphs, use that same period here instead of All. The three Motor Failure events are 40, 48 and 20 minutes, which add to 108.
Check the result
- In this sample, the Category graph on All shows six bars, with Changeover tallest and Breakdown second.
- The Reason graph with Downtime Category set to Breakdown shows five bars, with Motor Failure tallest.
- The Detail report for Breakdown lists eight events with a Total of 204, and its three Motor Failure rows add to 108.
Common questions
What do the bars on the Downtime Graph show?
In the account reviewed, each bar added up the Duration, in minutes, of the downtime events returned for one category (Category graph) or one reason (Reason graph) after the active filters. The vertical axis is minutes and rescales to the data, and the bars are sorted tallest first.
Why does the downtime graph show only one bar, or no bars?
In the account reviewed, the graphs opened on this month to date. A month with a single downtime event drew one wide bar, and a period with no events drew an empty axis and Total: 0. Open the Date field and choose All, or a wider period, before reading a ranking.
Why do the bars have no numbers?
The chart is drawn as an image with only the axis for scale. Read approximate heights from the axis, and use the Downtime Report - Detail with the same period and filters for exact minutes.
What does Total mean on the graph page?
In the account reviewed, Total counted the bars drawn: 6 categories or 12 reasons in this example. It is not a minute total.
Why are some labels cut off?
Long category and reason names run past the edge of the chart image. In the account reviewed, a label such as Scheduled Maintenance was clipped. The Detail report shows the full names.
How do I see only the reasons inside one category?
Open the Downtime Graph - Reason and choose the category in the Downtime Category filter. In the account reviewed, the Category graph did not have that filter.
Should the reason bars add up to the category bar?
With the same period, work center, asset and work order filters, they should, because each reason belongs to one category. If they do not, check that the filters match, and check events whose reason or category is missing, which this guide did not test.
Does the graph change any data?
No. The graphs and the Detail report only read saved downtime entries. To correct a figure, correct the downtime entry it came from, then reload the report.
