Create separate SKUs for prelam and postlam of the same core
Give pre-laminated and post-laminated versions of one core material their own SKUs so finish lists stay separate.
For finish-type catalogue items, the SKU is linked to a material record, and the platform enforces a strict one-to-one rule: a material already attached to any SKU cannot be attached to another. Creating a SKU with an in-use material fails with MATERIAL_ALREADY_ATTACHED; the same situation on update or bulk-create is also rejected (bulk create reports MATERIAL_ATTACHED_TO_OTHER_SKUS). This is why 'reusing' a material across two finishes requires cloning the material - the SKU clone flow does exactly that, duplicating the material for the new SKU automatically, and the bulk-update flow supports a material-clone option per SKU. Second behaviour worth knowing: when a SKU is created or updated with a material and no display picture is provided, the SKU's display picture is automatically taken from the material's picture (on update, changing the material always resets the display picture to the new material's picture). So a client asking 'why did my SKU thumbnail change after I swapped the material' is seeing intended behaviour - they should upload an explicit display picture afterwards if they want a different thumbnail.
When the same core material is needed both pre-laminated and post-laminated, create two separate SKUs (for example one named for prelam and one for postlam) so each gets its own material record and the finish lists stay separate.
Lamination type is declared per SKU on the catalogue side, on the core material's Lamination Type tab (Prelam Internal / Prelam External / Prelam Both / Postlam, with the linked finishes). Cloning such a SKU carries it over: a clone of a Prelam Both core material is Prelam Both with the same linked external and internal finishes.
The options are postlam, prelam on the external face, prelam on the internal face, or prelam on both faces.
