Could not able to post AR Invoice

Hi guys,

One of my client in singapore, when creating the AR Invoice the following error happens ..

They use Web service to post the invoice to SAP

Type sapb1.invoice.Document$DocumentLines$DocumentLine$DocumentLineAdditionalExpenses$DocumentLineAdditionalExpense$LineExpenseTaxJurisdictions$LineExpenseTaxJurisdiction not present

till two days before they were able to post the AR Invoice ...since today they could not post any AR Invoice ...

Have no idea why it happens ?

Any idea ?

Thanks

Gopi
