Understanding the Account Number Setup for Company and Contractors
You must use the TX2 (Additional Tax Id) field in the Address Book to setup the Company's account number.
You must use the TX2 (Additional Tax Id) field in the Address Book to set up contractor's account number. If the contractor does not provide the account number, leave the TX2 field blank or enter a value of 000000000RT0000, 000000000RP0000, 000000000RZ0000 or 000000000 for default company. In this case, the system uses the SIN value from the TAX field in Address Book. The system does not consider the suppliers with default company for summarization and reports them separately.
