How to create a new Movement Type from MTV 261 ?

Dear All

I create a new MVT, Y61, by copy from Mvt 261. Tcode OMJJ.

I assigned Tcode Migo into Allow transaction.

I run Tcode Migo, A07 Good Issue, R08 Order. Key in Order Number, Mvt Y61. Press Enter.

In the line item detail, movement type is 261. I wana change Mvt in line item detail to Y61, but I don't know how to config it

Please help me solve this issues

Thanks
