Hi Naga,

The way code is written differs for Inbound IDoc processing and Outbound IDoc processing.

For inbound, you usually write a function module to read the IDocs and post it in SAP.

The IDocs contain different segments and it is stored in EDID4 table.

The structure contains segment name, data of all the fields in the segment and hierarchy fields.

You have to retrieve the IDoc using the IDoc number, which is stored in EDIDC (IDoc Control data)table and that is the key for comparison between EDIDC and EDID4.

Before you start writing the code, it is necessary to learn the basic concepts of IDoc. You read the details you can move to your internal tables and then post using any BAPI or BDC.

For outbound, you have to collect your data from the SAP tables and then populate the IDOC structure depending on the IDOC type used. Then populate the control record with IDoc type, message type, partner number etc and then call MASTER_IDOC_DISTRIBUTE function module.

It would be good if are very specific so that SDN guys can reply your query easily.
