Print TO automatically

Hi Gurus,

I've define spool code and print code in T-code OMLV, and "print immediately" is activated for my spool code.

Now:

If i set field "immediate To creation " as "X" for my movement type in T-code OMLR.

TO can be print out automatically.

If i set field "immediate TO creation " as "A" for my movement type in T-code OMLR.

TO will not be print out automatically.

Do you know the reason ? i wanna my TO be print out automatically in second senario.

BR,

Dragsky
