Inbound Idoc programing

Question

Hi Gurus,
I will be getting the IDOCS from an external system which is also on SAP.
What I need to do is to get these IDOCS which are called Erroreneous IDOCS.
From the IDOC numbers I am able to see the message types and idoc types and data in the segments.
What all the steps and configurations I need to do for reading an IDOC data from segments and update on of the tables with the received data.
Do I need to write any inbound function module if so how. Please do let me know the steps and even what configurations I need to do?
Please help.
Regards
Mac.

Hi Mohan,
   External system means , yu can use EDI...
please check the following steps :
Phase : 1
ALE Configuation settings :
Create logical system: SALE
Create RDC destination: SM59
Create port: WE21 "Declare Port
Create partner profile: WE20 "Add port to Partner profile
Set up distribution model (If necessary): BD64
Phase : 2
*Define segments: WE31*
*Create new basic idoc type: WE30*
*Create message type: WE81*
*Link message type to IDOC basis type: WE82*
Note : Sap has provided huge standard idocs and message types , so my suggestion is no need to create new idocs and message types.
Phase : 3
Once you finished first two phases , then generate the program, we have three ways to develop the program. standard alone , messagetype and change pointers.
should be call : master_idoc_distrubute
inbound means : use the tranx codes : bd11 receiveing mat, bd13 receiveing cust,bd15...
once u finish, check we02 and we05....
