Complex Mapping :-Help Required

Hi All,

I have a scenario XI--IDoc.

Sender structure is having one field as Description which will carry some informatiom.I have to read the Summary Field and if I get XAA1:686,XAA2:767 or XAA3:876 like this  inside this  inside this field than I have substring  and take those value individually than we have to map it accordingly.

You can consider all these value will come separated by ,(comma) and based of the sbustring we have to map it.

Thanks,

Rakhi
