I am using multimapping to split a incoming idoc which has variable headers and variable line items...two two files ...one containing all the headers and anoth containing all the lineitems ...
so that finally I can have two files .
using two communication channels ...one for headers and one for lineitems .
each one should generate one file each containing all the headers and lineitems respectively.
Is this even poosible,
BPM is not the option ...
How will file communication channel would bundle all the headers or for that lineitems ...what should be settings there
want a fixed length file for each ..
what are things I can specify in FCC.
There are no settings to be done. Your approach what you are saying is absolutely fine. If you go ahead and do you will get two individual fixed length files.
You try to take a flat structure for Header and flat structure for items. You use context functions. With the help of this you will achieve this.
