Profit center splitting - Intercompany FB60 - Sales/Use Tax Vendor invoices

Question

We are implementing Use Tax calculations for Vendor invoices and are stuck on an issue with profit center splitting when entering intercompany AP transactions (FB60).     The tax postings of the non-leading company are being split between the two company profit centers.
When posting a vendor invoice with more than one company the tax items of the leading company are posting with the correct profit center but tax items if the non-leading company are splitting between the profit centers of the two companies.   The total amount of the tax is still correct, just part of it is posted to the wrong profit center. 
We are assuming this is a document splitting issue but changes to document splitting configuration did not get the desired effect of not splitting the tax accounts.   
Are there any suggestions of particular areas of document splitting that we should look into or other areas that might be causing this profit center splitting for the tax items?  Any ideas would be appreciated.
Thanks,
Jeff

Hi Murlidhar,
Here's a sample transaction with the problem results we are seeing.  Normal AP transactions are posting fine, it is only when Sales/use tax is added that we are finding a problem with the profit center splitting.
Entering a two line FB60 transaction under company 0001.
Line 1  - Company 0001, profit center 220020, $100
Line 2 - Company  0002, profit center 250020, $100
SAP sends this transaction to our external tax system which returns the tax amounts to accrue for each line item.
Line 1 $7.30 for company 0001
Line 2 $9.05 for company 0002
When the transaction is then viewed in General Ledger View we see the tax amount of $7.30 posting to profit center 220020 but the tax amount for line 2 of $9.05 is evenly divided between profit centers 220020 and 250020. 
The $9.05 should be posting only to profit center 250020 as the profit center assigned to line 2 of the transaction.
Thanks,
