In our implementation project we added new four trace dimensions using the standard extension framework. Here the link to documentation:
https://docs.microsoft.com/en-us/dynamics365/fin-ops-core/dev-itpro/extensibility/inventory-dimensions

We need to know if the framework supports inheritance of extended dimensions through intercompany transactions. The Batch dimension is inherited by the purch line transaction (and the related record in inventBatchTable is created if the batchid doesn’t exist in destination company) We expect the same behavior from the new added dimensions using the standard extension framework
