Asset Category not defaulting from Item Master at AP Invoice level

Summary:

We have created Asset Items and assigned them Asset Category at Organization Level in the Item Master. These Asset items are not being tracked in Inventory and have destination type as Expense when used in PO. Based on the Item Category to Natural account Mapping the PO Charge Account is being generated and the Asset Clearing account is being defaulted in PR and the same is being carried over to PO and Receipt. We have the Pay on Receipt option enabled wherein as soon as the Receipt is created the concurrent process runs and generated an invoice in AP.
