Purchase Order - Invoice tab Jurisdiction code

Hello,

This has reference to the Purchae Ordrer item detail.

In the delivery address "Say Address A" there is the postal code and region and based on this POSTAL CODE the tax jusrisdiction gets populated.

Now, if I change the delivery address, subsequently the tax jusridiction also changes accordingly. But, in th einvoice tab where there is the jusrisdiction code field, th eold one remains and the new one does not get overwritten.

This is an issue.

Any ideas and help please!!!

Best Regards
