Unable to Generate 2D Barcodes of Sufficient Length


We are creating PDF417 barcodes in Crystal Reports and printing them to a Zebra 110Xi4 printer (600 DPI).

In general, the DataToEncode of the PDF417 barcodes are using the following pattern:

PPPPPPPPYYYYMMDDSSSSSSS

Where P is the part number (up to 30 characters in length), YYYYMMDD is the date (8 characters in length) and S is the serial number (up to 8 characters in length).

Observations:
If the overall length of DataToEncode is set to 21 characters (or less), it can be scanned with our Symbol scanner. If the overall length exceeds 21 characters, it cannot scan.

What are your suggestions?

Operating System: Windows

Application: Crystal Report

Best Answer

Thank you for the clarification. While troubleshooting custom code is outside the scope of support, it seems that the issue is that the result in Point 2’s DataToEncode is being fed in as numbers, where our function needs the data-type to be a string (text).

Solution:
Try surrounding the entire right-hand side of the statement in cstr(), Crystal’s ‘convert to string’ function.

[Support Note: Modified to remove proprietary code and to make easier to read]

I am using Crystal Reports Native Formula for IDAutomation PDF417 Fonts (Version 2006.11a ) to generate the 2D data. If I restrict the overall length of the codified string, it will scan, otherwise, it will not.

These are my properties:

EccLevel = 0
ColumnSpecify = 0
RowSpecify = 0
PDFTruncate = 0



My Code:

DataToEncode = CStr({V_LMINVTRY_MANUFACTURED.CSERIAL}) & CStr({@Date}) & CStr({V_LMINVTRY_MANUFACTURED.PART_NO})

if len(Trim({V_LMINVTRY_MANUFACTURED.PART_NO})) >10 then
DataToEncode = ({V_LMINVTRY_MANUFACTURED.PART_NO}) & ({@Date}) & CStr({V_LMINVTRY_MANUFACTURED.CSERIAL})

else

DataToEncode = (Trim({V_LMINVTRY_MANUFACTURED.PART_NO}) & space(11-len(Trim({V_LMINVTRY_MANUFACTURED.PART_NO})))) & CStr({@Date}) & CStr({V_LMINVTRY_MANUFACTURED.CSERIAL})
end if
DataToEncode = (Trim({V_LMINVTRY_MANUFACTURED.PART_NO})) & ({@Date}) & ({V_LMINVTRY_MANUFACTURED.CSERIAL})


Point 1 - This will scan:
DataToEncode = "12345" & ({@Date}) & ({V_LMINVTRY_MANUFACTURED.CSERIAL})


Point 2 - This will not scan:
DataToEncode = (Trim({V_LMINVTRY_MANUFACTURED.PART_NO})) & right(({@Date}),6) & ({V_LMINVTRY_MANUFACTURED.CSERIAL})

To can analyze the issue further, very specific information is needed.

Please post all of the following (per barcode):

1. Example of hard-coded IDAutomation function - which is needed in the form of (this will allow data being encoded to be seen):

barcode_function_called("ABC123")

The function cannot be analyzed with dataset field names:

barcode_function_called([TableName])

2. A clear screenshot of the barcode resulting from #1.
3. A clear screenshot showing the encoded text from #2 (please change the barcode font from the field and assign a non-barcode font, like Arial or Calibri).
