Even type: Miscellaneous Transaction when are triggered Accounting Classes/ Journal line rules

Summary:

Hello, would be possible to get explanation how exactly are triggered these Accounting Classes/ Journal line rules under

Event Class: Miscellaneous Transaction

Event Type: Miscellaneous Issue/Miscellaneous Receipt

based on performed material transaction "case" done in Inventory management (misc. transactions in this case)?

Accounting method is a copy of the Oracle seeded one.

List of JLR:

• Expense
• Inventory Write-Off
• Miscellaneous Issue Variance
• Miscellaneous Receipt Variance
• Valuation unit transfer variance

The closest resource is: Overview of Cost Accounting Distributions (oracle.com)

But there are missing details.

According to the understanding it looks like these SCM Event classes contains additional JLRs that aren't used right now, is my presumption correct and only JLR mentioned in the guide above are actually valid?
