Material transfer between company codes with 303 and 305

Hi everyone,

Please, read through the process below and let me know if you can help me.

For a material transfer plant to plant between different company codes. I'm using a movement type 303 that in IM sends the material to stock transfer and it creates two FI document, one for each company code. After that, we do a 305 movement in MBSU moving the material from transfer stock to unrest. in the destination.

My question is, is there a way for this process to generate an invoice? Since this is basically a cross legal entity transfer, is it mandatory to have an invoice? If possible I don't want to use PO creation GI and GR for this. If I can do just with 303/305, I will keep like this.

Thanks

Antonio Rocha
