Accrue at Receipt for Expense Items

Summary

Accrue at Receipt for Expense Items

Content

Our customers uses only expenses items (licensing only for procurement) and defined all items as "Expense" items in the system.

For few business cases they would like to use Expense Items as "Inventory Item"(Accrue at Receipt). Normally Accrue at Receipt used for Inventory item. 

What is the implications if we use Expense items at "Accrue at Receipt" and impact on accounting side. Is this possible scenario without Inventory licensing.

what is the best practice to my business case? If required I will explain the scenario in-detail.

Highly appreciate your help & inputs.
