movement type in reservation

Hi

We are in a Classic Scenario environment and the requirement is for a certain type of material to create Reservations in the backend with a different Movement Type. Let’s say we have we need two movement type  201 for cost center and 241 for asset

I have assigned this value (241) for the movement type and set it up as default but it didn’t work, the reservation was still created with 201.

how can i manage two movement type in creating reservation

Regards
