hi,
Extension of Standard IDOC Type
Firstly of all, letu2019s talk out IDOC type. IDOC is the most important element in most of the interface applications, we use it to hold the real data which needs to be transfer between the business partners, IDOC Type is the definition of the structure of an IDOC.
SAP provides a lot of standard IDOC Types, normally we call them Standard Type. In this case, SAP has provided standard type DEBMAS06 for customer master, you can use transaction code WE30 to check its definition.
But DEBMAS06 canu2019t meet the requirement 100 percent, because the customer what some additional data fields which this IDOC Type canu2019t cover. So the project team decided to create an Extension based on this Standard Type, letu2019s say ZEX_DEBMAS06.
Create additional Segments
To create an Extension Type, we just insert one or more additional segment(s) under the proper segment(s) of the Basic Type. So firstly we need to define the additional segment(s) to hold the additional data.
In this case, we need to develop three additional segments:
ZSMTP, to hold email address
ZKNA1, to hold more address information
ZKNVV, to hold more sales information
We use transaction WE31 to maintain segment definition. On the initial screen, just enter the segment name and click u2018Createu2019.
The system will bring you to the definition screen. Here you enter the description and the data fields of this new segment,
One Segment Type can have multiple Segment Definitions, you can consider one Segment Definition is one version of a Segment Type. The name of segment definition canu2019t be assigned manually, SAP will decide the name automatically by suffix three numeric characters behind the Segment type name.
After you have entered all of the information on the definition screen, just save it and go back, you will see that a Definition entry appears
This new created segment will not work till you release it. To release it, just goes to Edit Set release. After you mark it as released, you can not update the definition any more. If you want to update, you must Cancel release firstly.
Follow the same way to create the other two additional segments,
As of now, the development of additional segments is finished.
Create Extension IDOC Type
After the additional segments have been developed, we can use them to create the Extension Type.
We use transaction WE30 to create an IDOC Type, to create an Extension, we need to tick the option u2018Extensionu2019,
After click the button u2018Createu2019, the system brings you to a popup window
Here you tick u2018Create newu2019 and type DEBMAS06 as the Linked basic type, also enter the description of your new Extension, and press Enter to continue.
You will get the IDOC definition screen, this is a hierarchy structure, just expand the top element, you will see the child elements.
Since our new segments ZSMTP and ZKNA1 needs to be append under the top element E1KNA1M, so click E1KNA1M, then click Create segment, a popup window will come out,
Enter the segment name which you want to append, and min/max number, click the green tick to continue, you will see the new segment has been inserted. Follow the same to insert the others. After these, you will see the Extension definition and till this, the Extension Type definition is finished.
Assign IDOC Type to Message Type
Before you can use the IDOC type youu2019ve just defined, you must assign it to a message type. Go to transaction WE82 to link the standard message type DEBMAS with basic type DEBMAS06 and extension ZEX_DEBMAS06 which is the one youu2019ve just defined.
might be this information is useful for u.......
