.

Symptoms:
=========
The validation error is:

Category: Rejecting
Severity: Normal
Brief: : Parser error - No matching parser schema was found. [ID=0x2010003]
Details: The data starting at position 0 is not recognized as a valid data transmission.
ID: 0x2010003

Environment:
==========
BusinessConnect EDI 6.x versions

Resolution:
===========
This issue occurs because BC is trying to generate the TA1 acknowledgement to send back to your trading partner, but it can not find the TA1 definition needed.

To resolve this issue try following:

1). Create a group called "EmptyGroup" under the 00401 interchange (you do not need to define any group properties).

2). Create a transaction called "TA1" under this group.  

You do not need to assign an .sef file or mapping files to the TA1 transaction. BC will find the correct files automatically.

Data starting at position 0 is not recognized as a valid data transmission.
