PS - 'Budget/Planning' Ledger in RPSCO, BPJA tables

Hi,

Could you help to advise what does the 'Budget/Planning' Ledger in RPSCO, BPJA tables mean? Is it related to whether Controlling area or object currency is used?

Also, may I know if the forecast values can also be extracted from the 2 tables?

Thanks!

Regards,

Vivian
