How can i segregate the service tax amount amongest business areas ???

Hi Experts,

some times my client getting invoices which contains expenses concerning more than one business area. We have to enter separate expenditure line items as well as separate vendor line items while making the entry. Things are all right when there is no service tax.

If the Service Tax component is included in the invoice then we can not segregate the tax according to the business areas as tax amount input option comes only once in case of first vendor line item entry in T.code (F-43).But when i am trying to enter the 2nd line item of the same vendor and in the same transaction then the "TAX AMOUNT" input field is missing from the screen.

can anybody plz guisde me so that i can segregate the Service Tax component amongst the various business areas.for ur information we have 4 business areas.

Plz guide .

full points will be awarded for the right solution.

Regards,
