Message type: E = Error
Message class:  FKK_ID_PT_SIGN - Digital Signature Portugal FI-CA/IS 
Message number: 603
Message text: Print pattern cannot be read; document & not found on the data base
No entry was found in the database for this document. The used document
number to access the database (tables DFKKEXTDOC and/or DFKKEXTDOC2) is
either not plausible or the document was not stored with a commit-work.
The system aborts the processing because no document can be selected.
Contact your system administrator.
Check your code to ensure that the document number you use is plausible.
In case the document number is plausible, you need to improve the system
performance to increase the chance that the commit-work is finalized.
You can also use further coding during the exception handling to process
multiple attempts to get/generate the print data.
