I am implementing SAP GTS for a customer. While working on a Inward Processing we wanted to have Customs Registration number on the customs document and also the end date for that.
We do not have the communications setup, hence the process should be manual.
While looking for the place to add this information, we found a field Customer Registration Number
This field is non-editable in change mode and as far as I understand can only be update using inbound IDOC. Is there possibility to manually add the Customs Registration number.
And also where to add the end date for this.
