SLA: I want add line descriptions to journal lines created in General Ledger: How can I identify wic

SLA: I want to add line descriptions to journal lines created in General Ledger. My question is: How can I identify wich Journal Line Types in SLA I should adjust?

In SLA you can see a lot of different Journal Line Types, how can I find out which Line Types are actually used in the current accounting proces?

In other words: is there a query to find out which Journal Line Types are currently used in R12.

This would make it a lot easier to indentify which journal line types a need to copy and adjust with a line description. Instead of copying and adjusting every available Journal Line Type.
