Because the parent-child relationship between Master
Issues and Subtasks sometimes reflects a complicated relationship, and
has certain rules associated with it, there are some restrictions on these
Issue types:
A
Subtask cannot be created of an existing Subtask—FootPrints only supports two-level parent-child
relationships. Nested
Subtasks are not supported.
A
Master Issue cannot become a Subtask of another Issue—As
stated above, FootPrints only
supports two-level parent-child relationships. Nested
Master Issues are not supported.
Master
Issues and Subtasks cannot become Global Issues or GlobalLinks—The Global Issue feature allows you to link
similar Issues together to be solved as one (for example, a System
Down failure that is reported by many users). While
this feature has some similarities to Master/Subtask Issues, it is intended
for a different function and has different rules. Therefore,
Master Issues and Subtasks cannot become Global Issues, nor can they be
linked to a Global Issue.
