Session automatically posting the document

Dear all,

I have one doubtu2026

Last time just run f.05 foreign currency revaluation,

Even I canu2019t select any session name,

After execution of the f.05 even I canu2019t post that document,

But after two day I found system posted that document.

How it possible?

Is it possible posting the document without select the posting, without execution of session name?

Can you explained me any one?
