Debugging SAP PI mapping based on manager query

Om

In one of my project, My manager asked me to verify specific parameter has been passed to target system or not, in delivery idoc from sap system.

As technical consultant, we could not find the corresponding filed in idoc.

but 

In this way, I have searched the right parameter in my idoc,

open the xsd structure of that idoc,

Search for the "reason code" and finding right segment in idoc.

As follows.

My manager query as follows

I have interface sheet, which was download from SAP PI message monitoring.

(save this as my reference)

I used this excel sheet to search based on my requirement.

identifying right idoc and mapping information.

 Searching sender idoc segment based on field description. for this i have opened idoc xsd searched the key word "Order Reason" as follows

Order reason corresponding filed name is AUGRU,

Now search this filed in mapping, where it is mapped to target.

copy the target field name and give it to my manager.

I hope , this would help you to solve your similar problems.
