"UP0001 A fatal error occurred" while parsing an XML document.
The following error message is issued to the PRTFILE during DT processing of XML input:
UP0001 Severity: 08
A fatal error occurred during parsing of XML document XMLinput at line 1, column 7005. Message text from parser is Expected comment or processing instruction .**** File: EDI.TE51INT.CPP(EDIUPXML) Line: 665 Func: SAXDIHandlers::fatalError(const SAXParse
The input file is missing an XML prolog prior to each message, e.g. <?xml version="1.0"?>. The first message contains the prolog, but it's missing from subsequent documents within the same input file.
Resolving the problem
Add the needed XML prolog ahead of each document.
