This error appears when you try to receive or reconcile a purchase order and one or more materials on that PO are assigned to a subcategory in your catalog instead of a parent category.
How to fix it (step by step)
1- Identify the material causing the error
Open the Purchase Order where the reconciliation error appears
Look for the material that failed during reconciliation or receiving
Take note of the Material name or item number and the category currently assigned to it.
2. Check the category structure in Ply
Go to: Settings > Catalog > Categories y Types
Search for the category currently assigned to the material
Check whether the category is a subcategory or a parent category
How to tell the difference:
A parent category will show at the top level (e.g., A1).
If it has an arrow icon on the left, it means it contains subcategories (e.g., A2). Click the arrow to expand and view them.
3- Update the material to a parent category
Go to Catalog → Materials
Open the material that’s failing
Click Edit
Change the Category to a parent category under the correct branch
Click Save
4- Retry the reconciliation
Go back to the Purchase Order
Retry the reconciliation or receiving action
If needed, run a category resync and try again
