In version 2005A there are 2 separate 'VAT Code' fields in Business Partners table in PLD for marketing documents. If you have a look at the list and choose the second one, it will display the VAT Code from the BP Master Data -> Accounting tab -> Tax tab.
So create a new database type field, in Properties -> Content tab: Table is 'Business Partners', Column is 'VAT Code' - but choose the second on the list.
I'm not sure if it's the same in other versions, but in 2005A the scenario is the same for all the patch levels.
once u entered the VAT no in BP master Data (under accounting , Tax Tab, Tax Information in field 'LST/VAT No.') it will be taken automatically to the marketing documents. So when u raise a sale order, in tht document the VAT no will get displayed in the TAX tab, 'Tax Information' So in Sale Order PLD u can grab the value directly from RDR12 Table, field TaxId2.
To get RDR12 Table, in ur PLD create a DB field. Hold ur 'ALT' Key pressed n click to choose the table. now u 'll see all the tables displayed. Select the table 'RDR12 -- Sales Order - Tax Extension'
and choose the field TaxId2.
S. But cant view as individually the tables.
All the related tables are segregated under single name, like all the tables having details of Sales like Order, Delivery... n their Tax details, Tax info are all segregated under Sales A/R.
U can Browse in Report Composer and again from Report Designer u can expand rows for any specific terms and via Formula Builder u can view all the tables n its fields.
