The $ symbol denotes the secondary name space (source of fields). It can be used in every system function in which two or more items are available to evaluate the expression.
The following table shows the system functions in which a $ symbol can be used, and the primary and secondary sources.
System function | User interface | Primary name space | Secondary ($) name space |
---|---|---|---|
Create | Field to Assign | Newly created | Existing (creator) |
Expressions | Existing (creator) | Newly created | |
WaitForCondition | Field to assign | Waiting | Waited-for |
Expressions | Waited-for | Waiting |
For example, in the Create system function, you can assign a starting value to a data field in the newly created work item.
You can also assign a value to a data field in the existing work item.
