First year filling taxes for US multi member LLC with foreign members with no ID No. creates error on Form 1065

Our US multi member LLC has 2 US citizens members and 2 foreign partners. When filling form 1065 we get an error on the foreign partners ID No. Since they don't have social security number nor ITIN. What should I put on schedule K-1 form 1065 Part II. E to be able to finish filling our company taxes? 

From what I understand, the foreign partners need to apply for an ITIN number using form W-7 and in order to apply for this, they need to include the tax return that needs the number and a valid identification for the person needing the number.
