Custom process code and FM for custom IDoc...

Question

Hello Experts,
I created a custom IDoc based from ARTMAS05 IDoc. This is because we only need 3 segments and
the standard idoc(Artmas05) contains so many segments that we need.
Now, will I create a custom process code and FM for this? how do I go about this?
Thank you guys and take care!

Hello,
             Here are the Steps that we need to be following while creating a Custom Process Code with Custom Function Module. ( Since the Segments to be handled are very Less, I am recommending that you go for a Custom Function Module).
1. Go to SE37 Create a Function Module. Please ensure to Create it with the IMPORT / EXPORT /TABLES parameters exactly in the way that they exist in any Standard SAP Inbound FM (Refer to IDOC_INPUT_ORDERS for example).
2. Once our FM is Ready (Need not be Complete with the Code to go ahead with the Process Code Creation) and Active, the next Step is to Create an Entry in the Transaction Code BD51 where we will register the Function Module.
3. Next, we'll have to go to T-Code WE57 where we'll have to make an entry for the Function Module with the IDoc Type & Message Type.
4. Finally, go to WE42 and Create a New Process Code and assign the Function Module and the Message Type.
NOTE 1 : The Process Code is, as we know, Client Dependent. So, once you create a Process Code, we need to have it migrated to the Testing Environment to Start & Carry Out Testing.
NOTE 2: If Step 2 & 3 are missing, then we'll not be able to assign the Function Module in WE42 while Creating Process Code.
Hope it was helpful.
