File to file bypass scenario
we need pick the file from source folder with particular format filename .
filename is for example: BC01100000000032014_FC.xml
1 --> is the environment code
0000000003-->the next 10 digits are the SAP document number
and 2014--> the next 4.. are the fiscal year
_FC: are 2 digits and depends of the document type .
apart from this format PI will not suppose to pick the file .
