Example
Project MV Ocean Star – Dry Dock needs categories in order: 1 = Preparation, 2 = Steel Work, 3 = Coating. Create three mappings with Display Order 1, 2, and 3. Tasks created under each category follow that sequence on the Project Category tab inside the project view.
FAQ
Can I map the same category to a project twice?
No. Each project-category pair should exist once. Edit Display Order on the existing mapping instead of creating a duplicate.
Does Display Order affect task scheduling?
Display Order controls how categories are listed on the project's Project Category tab. Task WBS and schedule dates are set on individual Project Tasks.
Do I need a mapping before assigning a category to a task?
Best practice is to map the category to the project first. Assign Template creates mappings automatically from template task categories.
Can I delete a mapping that tasks use?
Delete removes the mapping record. Tasks already assigned to that category retain their category field — recreate the mapping if you need it on the project tab again.
Is manual mapping required if I use Assign Template?
No. Assign Template creates mappings for every category referenced on the template's task rows.
Can one category map to multiple projects?
Yes. Create a separate mapping record for each project that uses the category.
