This article is one of the worked examples in RCM. It shows how to list when changes were made to RCM analyses, and by whom. For when and why to use a query in RCM, see RCM Queries – Background; for day-to-day query tips, see Working with Queries.
In IMS there are two standard ways to list the RCM activities that have been done over time. Alternatively, if the list is long, a Query can be used.
Standard Methods
Option 1
In the Systems Main Screen (Grid List), the column #ALHY shows the number of analyses done in the last six months.
Example: In the first system shown here there are 4 FLOCs, 4 FMs, and 2 analyses done in the last six months:
Option 2
Take a look at the Event History on the FLOC/Equipment details page.
Example: There are 10 events listed for Pump001.
Note
You can export the Event history to Excel, if the list is (too) long. However, these methods are ineffective if you would like to list a large set of RCM changes.
Using a Query
If you would like to list a large set of RCM changes, you should use a query. See Custom Queries Editor for how to open and build a query in general. The video below also shows the process step-by-step:
To create a specific query, do the following:
Go to the Custom Reports Main Screen.
Click the Plus Button.
Enter the Query Name: "RCM Analyses changes".
Select the Base View: "RBITagAnalysis".
Then select these objects:
FLOC
Equipment
CMMS type
Equipment group
Location Type
vwRCMSitePlantUnit
Failure Mode

Select the fields shown below for these objects.

Select the following criteria for the fields - by clicking the Plus button. Active Equipment may be removed if not needed, by clicking the X button.

Take Note
Having the criteria on the "RCMFunctinalFailureID" ≠ 0 is essential for the performance of this query.
In the end - the output can show a lot of changes and look like:

To create, modify, and manage Queries, also see Custom Queries Editor.
Listing Analyses and Task Changes Separately
Create the following query to list Analyses changes and, separately, Task changes.
This output looks like this:

Note
Some text changes in the Task might not be seen as an Analyses change.
