Incorrect movement type 643 between plants with same company code

Hi experts!

Our company is customized as Retail, and I'm trying to create a new STO order from an store plant to another, but at the delivery it determines 643 movement type, and at the time of goods issue I get the error message M7 153.

It should determine 641 movement type, because the store plants belong to the same company code. Why this could be happening?

We have other transfer orders from suplying plants to store orders and then a 641 movement type is determined.

Thanks in advace to anyone who can help,

Maite.
