Edit BRM Mappings

Here you edit the mappings between a subsystem and the Interior BRM. The BRM can only be mapped to the subsystem level, as shown in this diagram. In Phase 3a, you can't edit primary BRM subfunctions. That capability will come in Phase 3b.

Text at top

The top of the window shows what system you are working in and where it is.

Levels

In Phase 3a, you can't edit primary BRM subfunctions. That capability will come in Phase 3b. Click in the checkbox beside a line to map that line. Do NOT check any DOI-tracked systems unless you know what you are doing; once checked, these cannot be unchecked. To make it easier to find checked lines, no line shows up opened into sublevels unless one of the sublevels is selected. This picture has the sublevels opened only for illustration--since none of them are checked, normally none of them would be opened up.

Where you go next

"Find" opens up a popup window that eventually returns you to this screen. "Save" and "Cancel" will both take you back to the main screen.
