Message text: Number Range Object not registered for Company Code &1 for Fiscal Year &2
The used number range object sequence is not declared in the
Registration Table for Numbering/Reporting Rule in Portugal.
It does not exist or the system tries to access the sequence for a wrong
fiscal or a wrong company code
A trusted document sequence cannot be determined. The processing is
stopped.
Once you have changed the settings to create the missing legal number,
you need to process the document again.
Check if an entry is missing  in the <ZK>Registration Table for
Numbering/Reporting Rule in Portugal. </>Declare the missing number
range object sequence.
If an entry exists for the number range object sequence and if you have
created your own event 1190, you will need to change the logic to create
legal numbers in event 1190 since the number range object sequence
determination is incorrect for the company code/fiscal year.
If you are using the standard event 1190 (FKK_EVENT_1190_XX_GEN), check
the entry in the <ZK>Registration Table for Numbering/Reporting Rule in
Portugal. </>
