Tax indicator in vendor master

Hi Expert,

we are implementing VAT, configured all required settings and tax codes are created and tested. but while determining tax code in PO we have the following requirement

Tax condition in PO: MWVS

for the above condition type is maintained with access sequence with following fields

• Tax indicator for material (field in material master purchasing view)
• Destination country(Structure field in KOMK)

tax code determination is perfectly working when we maintain the condition records with country key, Tax Indicator in materials master and the tax code. But the user wants to restrict the tax code determination using and indicator in the vendor master so the at he should be able to maintain the condition records as follows

• Destination country
• tax indicator for material
• Tax indicator in vendor mater(which we are not able find)

we have tried using the tax type in the vendor master control view but the somehow system is not able find the access the condition maintained the condition records.

Please find the attached below detailed screen shots.
