-5. Reference data (Position Number)
+5. Reference number (Position Number)
 Search the document for our internal "Position Number". It always follows
 this structure, regardless of how it is written on the invoice:
-
   [2 letters][3 letters][4-digit booking period YYMM][3-digit sequence number]
+For example: 
 
-Standard formatted example: IM-GCA-2607-100
-  - "IM"   = 2-letter code
-  - "GCA"  = 3-letter code
-  - "2607" = booking period (YYMM, i.e. year 26, month 07)
-  - "100"  = 3-digit sequence number
+ - IM-GCA-2607-100
+ - LA-PAP-2408-030
+ - IM-LUF-2409-065
 
 Vendors frequently omit the separators or use different separators when
 printing this number on their invoices, e.g.:
   - No separators at all: "EXGCA2608009"
   - Spaces: "EX GCA 2608 009"
   - Dots or slashes: "EX.GCA.2608.009" / "EX/GCA/2608/009"
-
 Search the entire document text for any substring matching this pattern
 (2 letters, 3 letters, 4 digits, 3 digits — in that order, with or without
 separators between the groups). The 4-digit booking period (YYMM) is the
 most distinctive part of the pattern and can help you locate it.
-
 Once found, extract it and output it normalized into the standard format:
 XX-XXX-YYMM-NNN (e.g. "EXGCA2608009" → "EX-GCA-2608-009").
-
-Do not confuse this number with other codes, order numbers, or customer
-numbers that may appear on the invoice.
+Do not confuse this number with other types of identifiers, such as order
+numbers or customer numbers, that may appear on the invoice but do not
+match this pattern.
+If no reference number with this pattern is found leave the reference number blank. 
+If multiple reference numbers in the document match this pattern, select the
+first one that appears in the document. Do not add any comments or explanation about the reference number.
