call BAPI_PO_CHANGE from ME22N and go back with F3

Hello,

could anybody confirm to me if it is technically possible the following process:

- execute ME22N

- call the BAPI_PO_CHANGE from transaction ME22N (through one added button in program SAPLXM06 and screen 0101)

- call BAPI_TRANSACTION_COMMIT

- go back to ME22N (F3)

Thanks !
