Extract Field from file
I have a scenario in which i am collecting IDOCS(900-1000 number) in the form of a file (as given in Steffans Blog).
File adapter picks up this file and posts this file to target.
My requirement is to extract a field value from this file .This field value is unique for all the 900-1000 IDOCs collected(into the file).Before posting the file at target i have to add this field as a header to the file.
for eg:if all the IDOCs collected has a unique field called ACKKEY and has a value PET500, my target file should have the header field at top as
followed by the contents of the field.
Should i write a user defined function for this?or is there any other way?
If i have to write any user defined function for this what is it to be(i dont know much about how to write java code)?
I will award points for sure
