Page designer grid list inventorypart

Hi ​@pongenae ,

You can’t add that field directly in Page Designer the way you’re thinking.

The reason is:

• InventoryPart and ManufPartAttribute are different entities
• Page Designer only works with fields that are already exposed in the projection/view
• It does not support joins or pulling fields from another entity on the fly

So even though the data exists in ManufPartAttribute, it’s simply not available to the InventoryPart grid unless it’s exposed in the backend.

What you need to do instead

You have two workable approaches:

1. Extend the projection (recommended)

• Identify the projection used by the Inventory Part page
• Create a custom projection extension
• Add:
  • a join (or reference) to ManufPartAttribute
  • expose the IssueType field

Then:

• In Page Designer → the field will appear
• You can add it to the grid

2. Create a custom field (if simple mapping)

If IssueType can be derived or stored:

• Create a Custom Field on InventoryPart
• Populate it via:
  • Event / BPA / logic

Then:

• Add it directly in Page Designer

Important limitation

Page Designer cannot:

• join entities
• fetch fields from unrelated LUs
• calculate values across entities

 It only works with what the projection already exposes

Practical tip

Before customizing:

• Check if IssueType is already:
  • available via a reference field
  • or another projection

Sometimes it’s already there but not visible in the UI.
