Variable Substitution Issue:Content is not allowed in prolog.

[manikandan_shanmugam3]

Hi All,

I am getting below issue on Variable Substitution.

I have checked the payload it doesn't have any space or special chars but numeric value 120.

SAP PO 7.4

Confug:

var1    payload:MT_Test,1,Segment,1,TrxType,1

Folder Cnfig:List_B%var1%_.csv

MP: exception caught with cause com.sap.engine.interfaces.messaging.api.exception.MessagingException: com.sap.aii.adapter.file.configuration.DynamicConfigurationException: Error during variable substitution: com.sap.aii.adapter.file.varsubst.VariableDataSourceException: Caught SAXException while parsing XML payload: Content is not allowed in prolog.

Regards,

Mani

Hi All,

Thanks for your support.

The issue was solved. It was not working as I was doing FCC conversion through modules.

Hi Manikandan,

Have you checked your XML before the mapping?, are you sure is correct?, can you validate it against your xsd schema (XML Validation: XML Validation)?

Also you can check this Shabarish's blog as well ?

Check the file using a hex editor to see if any Byte Order Mark characters are there in the file.
