Hi, i'm trying to save Transaction but its throwing following error

Unable to save the transaction due to an error being reported by the tax calculation engine:

Tax Calculation Plugin error due to a server-side SuiteScript exception: Transaction Type Determination Error: the transaction cannot be saved. The transaction contains items with different types of VAT regime determination. Please create separate sales transactions for goods and for services.

Any idea why ?

sentence before last tells you why. last sentence tells you how to fix it.

Any workaround for having sales transactions for goods and for services.
