Create validation in Tax Number CNPJ

In order to develop a validation within extended fields that do not exist as standard as the TaxNumber in SAP CRM related to TaxType “BR1” in Brazil, follows the algorithm model that is possible used to perform validation tax document CNPJ.

This procedure can be improved and optimized by reusing libraries and loops

The following coding is only an initial reference

Create the follow objects

Put in the Validation “OnSave” the follow code

       var cnpj = this.CurrentCommon.CNPJ;

Remember to create the following object to use of the extended field for use principally on screen
