Change Tax Jurisdiction code (TXJCD) in Cost Center Master Data

Question

Hi There,
We have a problem of making change to Tax Jurisdiction Code in Cost Center Master Data. We are on ECC 6.0 with Vertex system as external tax system. When we create Cost center, system automatically derive tax jurisdiction code from vertex) external system).  Now Vertex have made changes to Tax Jurisdiction Code for same place based on US Gov directive. these changes are time period base say from 01/01/2008 to 06/30/2009 Tax Jurisdiction Code  "TX1000" and from 07/01/2009 to 12/31/999 Tax Jurisdiction Code  "TX2000" (example)  When we go to change mode in Cost Center, system automatically derive the new Tax Jurisdiction Code  and update the cost center with new Tax Jurisdiction Code  "TX2000". When we book invoice for cost center, with back date say 06/29/2009, system through the error, that it is not a valid Tax Jurisdiction Code.
My question is; how can we maintain two different Tax Jurisdiction Code  in SAP for Cost Center? From configuration stand point of view, we have maintained TXJCD as time dependent field, but still this field is grayed out and sytem populate the Tax Jurisdiction Code  from external system, since we have installed vertex system for tax purpose.
Please let me know.
Thanks,
Pawan Sharma
