Functional Requirements (Required before implementation):
- In the UI, there is a variable exists filter that accepts a variable name (but not a value)
Technical Requirements (Required before implementation):
- Nothing in addition
Limitations of Scope (Optional):
Hints (Optional):
Implementation options:
- This can be implemented either only in the frontend by translating it to a process variable like search with a full wildcard (needs validation that the Wildcard semantics are the same on the supported databases)
- It can be implemented as a dedicated backend filtering option
