R12.1.3 Service Requistions

1)

when we create a service Requistion > go to to distributions > assign the account> Save it > getting following error refering to taxes right after click on Save.

This req is however saved after the throwing the error.

2) Sending for approval.

Both errors seems related to set up of  taxes in E-Business Tax Module ( Tax Manager Resp).

Since the taxes are standard govt taxes and calculations, does anyone has document with setup steps required to fix this error.

This is in US operating unit. We are getting same error in Mexico org also.

Please advise.

thanks
