Movement type restriction

I created two Ztransactions i.e.ZZ309 & ZZ311 to 309 & 311 movement types under standard transaction code MB1B.

whenever i enter t.code zz309 by default movement type shows in the screen 309 in inactive mode.

After completion of processing and generating document number when it comes to the initial screen, at movement type 309 it is allowing us to enter any other movement.

Now my query is after processing the entire process(after document creation) when it comes to the initial screen it should restrict 309 in inactive mode only.

pl.explain the steps to restrict at initial screen.
