Withholding Tax - Not able to update

Dear All,

We have upgraded SAP 8.8 PL14 from SAP 2007B. With respect to TDS, we have upgraded based on the TDS Utiltiy Upgrade. Everything upgraded Properly. But, when we try to edit or change on Withholding tax definition or TDS account, an error is coming "This Property Cannot be Updated". Becoz of this we are not able to continue the entry on Particular Section. We are not able to add new WH Code also, since the same error is coming.

Pl help and sugges how to solve this.

Thanks.

Sundaram Raghavan.
