FX gain loss

Hi,

I'm a beginner trying to get my head around foreign currency transactions. I'd appreciate some help. I've read many answers here related to processing EBS with foreign currency transactions, however I still have some questions:

- Does Note 999974 relate to automated posting? Original text that I came across indicates only Manual posting.

- If so, is there FX gain/Loss since there is no FX rate difference ?

- How does above relate to the setting in T-code: OBY6, the flag of 'No ex.rate difference when clearing in local crcy' ?

Thanks in advance !
