Exchange rate used for automatic postings CATS - process unposted time

[SAPSupport]

Hi,

I am facing an issue with the GL account and the exchange rate type.
I've tried to check in the SAP documentation, but I couldn't find something related. Could you please let me know why for the documents transferred using CATS is used exchange rate type P instead of M? Only exchange rate type M is maintained during the year. Also, where can I find in the configuration this setting?

Adding why exchange rate type P is used during calculation:

To prevent currency fluctuations in the activity allocations.
