Can't find custom field name in IBM RTC

Question

I have a custom RTC work item with the field 'Business Unit (BU)'

I need to find the API xml element name for this item, in the past I've been able to find them no problem by going to a url formatted like this to see the xml data:

https://company.com:1111/ccm/oslc/workitems/252829

Where 252829 is the id of the work item, but if I control + f search on this page for Business Unit or business or even the value 'AMI', there are no results, all the other fields show up fine except for the one i need, Business Unit (BU).

Does it have something to do with the lightbulb button next to the rtc value? Do I need a different url in order to view tall the rtc xml values? I was hoping it would be something like rtc_cm:BusinessUnit

Answer 1

The icon (lightbulb + list) should have a label.
For instance, as in this thread, "guess category".

"The Guess Category button attempts to guess the correct category by using the text in the Summary and Description fields to search for similar work items."

As I understand it, it doesn't look for a similarity between the text and the category name ... it does a search for the work item whose summary/description is a best match for the text, and then suggests the category of the work item.
Try typing in words that match the summary/description of some existing work item.

In other words, if this is a dynamic field based on a runtime search, you would not see any static value when you go to URL you mention.
