Problem with BAPI_MATERIAL_SAVEDATA

Hi.

I'm having a problem when creating new materials with FM 'BAPI_MATERIAL_SAVEDATA'.

First, I'm taking a new material number with FM 'BAPI_MATERIAL_GETINTNUMBER', the number is generated without any problems. After, I try to create the new material, I have a message of 'SUCCESS' (Material have been created), but when I come to MM03 to see it, the material have not been created. I'm using COMMIT WORK after these BAPIs.

Please, help!

Thanks and Regards!
