Hi,
For outbound IDoc the program can be found:
1) For master IDoc via transaction BD60. Here for the message type you can find the function module used to generate the IDoc. Within this function module you can find the user exit where you can code your logic.
2) For IDocs with message control (output control) we maintain settings for proces code in WE41. This process code will lead to outbound IDoc generation program.
For Inbound IDoc the program can be found:
Via WE42 where inbound process and its related inbound function module is maintained.
In each cases above we can go the function module and find the customer exit where idoc enhancement logic can be coded.
For extending IDoc look at the following links:

It can be summarized as follows:
Enter transaction WE30 (ALE->Extension-> IDOC types->Maintain Idoc type)
- Type in your name of the extended IDOC type (usually starting with 'Z') and click on the Basic IDoc type, click the create icon.
- Click on Create new and enter a description and press enter.
- Click on ZIDOCTYPE01 and then on the Create icon.
- Enter ZIDOCTYPE as the segment type, click on Segment Editor.
- Enter a description for your segment type and create.
- Enter a description for your segment, enter each field required in your IDoc and press enter to validate.
- Save and generate, press back
- To release the segment choose Goto, Release from the menu.
- Check the box on the line of your segment.
- Save, back and enter.
- Your Idoc type structure should be displayed with your new segment.
- Save and back.
- To release the Idoc type choose Extras, Release type from the menu and Yes.
Hope this helps.
