While doing a batch update on several products I used an interface to update the cost field. I just used code, description, product (code+description) and cost fields in the interface (from the accounting module).

I run the interface and it created a new product without the code. The problem is that the UoM of the original code, was changed from "Piece" to "m" (meter).

The other problem is that I didn't notice the first problem and created an inventory movement. So now the system does not allow me to make the correct update.

I reproduced the error without the inventory movement but is the same, previous inventory movements of the original product were done in "pieces" and the new ones can't be done because the UoM is "meter".

So, the interface wrongly changed the UoM, any solution?
