We receive an SAP IDOC using the WCF adapter; afterwards, the disassembler uses that input file to create an XML document. When we later want to re-create an IDOC flat file from that XML document, the assembler does not create blanks for fields that had been empty in the input file - though they are marked as mandatory fields in the schema.
In this example, you can see the missing blanks in front of the "INVOIC" segment in the output file.
Input file - 2 blank segments in front of "INVOIC"
EDI_DC40 3000000000000526082700 3012 INVOIC01
XML - no tags for the 2 blank segments, which seems okay:

Output file - missing blank segments in front of the "INVOIC":

If anyone knows a solution, please comment. If we find one, we let you know this here.
