Customizing the Tax Calculation Procedure 

Use

By default, the tax calculation procedure for Mexico cannot handle tax codes that contain multiple deferred tax conditions. This is the case with IEPS tax codes, which contain two deferred tax conditions, one for deferred VAT and IEPS.

So that the tax calculation procedure can handle such tax codes correctly, assign a requirement to the appropriate conditions as follows.

In Russia, the standard tax calculation procedure comes ready customized. Instead of requirements 150, however, it uses requirement 166.
