Biztalk Schema for missing values

Question

I have a biztalk 2013-r2 schema for a txt file, that sometimes does not have a value for the last column.

With value:
Name, address, city, state, zip, phone
Mike Myers, 30 West Street, NY, 10001, 2124444444

Without value:
Name, address, city, state, zip, phone
Mike Myers, 30 West Street, NY, 10001, 

When the column has value, there are no issues.

When the last column has no value, I get the following error:

PublicKeyToken=92c4a30afea05f3e" Source: "Flat file disassembler" Receive Port: "rp_List" URI: "C:\BiztalkTestFiles\List\myfiles\*.txt" Reason: Unexpected data found while looking for:
'\r\n'
The current definition being parsed is Mydefinition. The stream offset where the error occured is 101. The line number where the error occured is 2. The column where the error occured is 6.  

Is there a workaround for this type of issue?

Answer 1

Usually you simply set the Min Occurs on the last element to 0

Also make sure that your records do actually finish with a CR & LF (use NotePad++ and show All Symbols)

The fact that it is complaining on line 2 column 11, your problem may actually be something else.
