When i confirmed a quotation, i got the error below.:

The unit of measure m² defined on the order line doesn't belong to the same category than the unit of measure Unidade defined on the product. Please correct the unit of measure defined on the order line or on the product, they should belong to the same category.

But this specific quotation has 59 products and each with it's own bill of materials and correspondent dozens of raw materials in each BoM.

I've tried opening all product in the quotation, and they're all correct. How do i find which one is wrong? I've spent hours creating this quotation, and have many more like these. I'm afraid i'll have to recreate everything again, and i could loose weeks in the proccess.... :(
