Digital Signature Apps for Portugal >> Maintain Document Number Gaps and Generate Digital Signature for Billing Documents(Maintain SD Document Number Gaps).

The issue occurs because there are gaps in the sequential numbering of billing documents. Due to these gaps, the system is unable to generate a digital signature for the affected billing document, which prevents printing.

Step 1: Maintain Billing Document Number Gaps

• Open Maintain SD Document Number Gaps – Portugal app
• Enter: Number range (No)
• Missing billing document number(s) in Billing Doc.
• For intervals, use From–To fields
• Click Save

⚠️ Ensure only truly missing numbers are maintained. Maintaining incorrect or existing numbers will break compliance.

Step 2: Generate Digital Signatures

• Open Generate Digital Signature SD – Portugal app
• Enter: Company Code, Number Range
• Click Execute

Example: Billing documents from 10001 to 10005 in number range XX

• 10001, 10002 → Signed
• 10003 → Missing
• 10004 → Exists but not signed
• Maintain 10003 as gap
• Run Generate Digital Signature SD – Portugal for the number range to sign 10004

Result: Sequence becomes valid → Printing of subsequent documents succeeds
