How to create a IDOC program

Question

Hi All
i have a requirement where i have to design a screen program to provide the user with a input screen. The user will input data on this screen, after the user enters the data and clicks on execute or some button on the module screen the system must generate a IDOC in the system. This IDOC will be picked up from another program within the same system.The reason we are doing this is the other program cannot be changed and it can accept only an IDOC from the external system which we are going to eliminate.
My Questions:
1. What are the steps in this requirement
2. Do we require the partner profile and port and logical system definition as i am going to create a IDOC in the same system.( i am not sending the IDOC out of the system)
3. Can i use the MASTER_IDOC_DISTRIBUTE FM to create a IDOC in the database?
4. Can i use IDOC_CREATE_ON_DATABASE FM to do the same job?
please guide me with deatils on how to go about this. Thanks

Assign the tcode to the IDOC.
or else get the data into IDOC segment and try to transfer it.

Assign Idoc Type to Message Type ( WE82)
Creating a Segment
Go to transaction code WE31
Enter the name for your segment type and click on the Create icon
Type the short text
Enter the variable names and data elements
Save it and go back
Go to Edit -> Set Release

Create IDOC Type
Go to transaction code WE30
Enter the Object Name, select Basic type and click Create icon
Select the create new option and enter a description for your basic IDOC type and press enter

The system transfers the name of the segment type to the IDOC editor.
