Hi Friend,

my file patern like that "extract_CES_SAE_v2_ t0002854gt9q_*.pgp".

My quiestion is

is there any module configuration is need for this?

or any option is available in SFTP?

One more question: is it different for module key sender and reciever side?

or use same module key for both side?
