When working with a detached spare part list that has a multilevel hierarchy, we observed the following behavior:
-
The Level 1 part in the detached spare part list has two connected child parts (Level 2).
-
When retrieving the detached spare part list from the Maintenance Material Requisition (MMR), it is not possible to directly navigate or view the Level 2 parts from the hierarchy.
-
To access Level 2 parts, we need to manually add the corresponding Level 1 part in the MMR, then re-query and add spare parts from the detached spare part list. Only then do the Level 2 parts appear.
-
This process results in multiple iterations when dealing with hierarchical spare part structures. Additionally, once the Level 2 parts are retrieved, the previous level label does not provide contextual information about the parent part.
We’re trying to understand whether this is:
-
A system limitation by design in handling multilevel hierarchies within detached spare part lists; or
-
A potential enhancement opportunity, for example, having a “Next Level” or “Expand Hierarchy” command on Level 1 part lines to retrieve Level 2 (and below) parts more intuitively.
Appreciate insights from others who have encountered similar behavior or implemented workarounds.
