Item Tiles Placement Logic

The noncontextual item types (Manufacturing Assembly, Manufactured Material, Provided Part, Manufactured Part, and Manufacturing Kit) under the same parent item are placed as per their relative order in the PPR tree.

The contextual item types (Installation, Transform, Remove Material Types (Drill, Pre-Drill, No Drill, Cut, Grind, and Bevel), and Split) under the same parent item are placed so that the predecessor-successor relationship appears in the tiles. Only the contextual items, which are predecessor to a successor, follow the PPR tree order.

The groups under the same parent item are placed as per their alphabetical order.

Also, under a parent item, the groups are placed after both contextual and noncontextual items are placed. This is because groups, which are logical entities, do not appear in the PPR tree.

In the above figure:

• Root_MA, MA_3, MA_4, MA_5, MA_6, MA_7, and Provide_8 are noncontextual items.
• Install_10, Install_11, Install_12, and Install_13 are contextual items.
• GroupA and GroupB are groups.

The placement order of these items and groups is as follows:

1. The children of Root_MA (MA_3, MA_4, and MA_5), which are noncontextual items, are placed as per their PPR tree order.

   MA_5 of GroupB and MA_7 of GroupA are placed after noncontextual items as they both are inside a group.

2. GroupA and GroupB are placed as per their alphabetical order. Hence, GroupA containing MA_7 is placed before GroupB containing MA_5.
3. Install_10, Install_11, and Install_13, which are contextual items, are placed:
   1. Install_10, Install_11, and Install_13 are placed first to maintain the predecessor-successor relationship, which is not clear for contextual items in the PPR tree.
   2. Install_10 and Install_13 are placed together as they have a common predecessor (Install_12). They are placed as per their PPR tree order.
   3. Install_11 is placed after Install_13.
4. Install_12 and Provide_8 are placed.
