Jurisdiction code error message in MIRO

Hi,

I have hidden a field "Smart Number" in all the layouts available in MIRO transaction as this field was not wanted in MIRO. Now I am trying to post an invoice verification for a scheduling agreement using the screen layout "9_6310 Purchase Order - Entry Sheet" in MIRO. System throws me an error message "Enter Jurisdiction Code". If I change the layout to "2_6310 Purchase Order - Delivery Note", system does not throw me any error. Does this error message appears because I made the "Smart Number" field hidden in screen layout configuration?

I have attached the screenshot of the error message.

Please suggest.

Thanks

Sat
