EDI and IDocs
These groups of related data are called segments. Therefore, an IDoc consist of several
segments. Some segments are mandatory in the IDoc (such as address data),
while others are optional (such as dangerous goods data, which is not required if
the goods in question are not dangerous).
These segments have a special name: the segment type. They have a fixed order
within an IDoc type and can be nested. The same segment can occur multiple
times; for example, the segment type “Packaging data” could have multiple subordinate
segment types called “Packaging data per handling unit.”
Start Transaction WE30 in order to view an IDoc type. The system will ask you for an
object type, which means the IDoc type or the basic IDoc type. Open this field. The
system then generates a list of several possible IDoc types. You can see in Figure 16.7
that 1,198 basic IDoc types are set in the system.
Figure 16.7 Overview of All IDoc Types
As before, the same IDoc types can occur here several times, as IDoc types are
adjusted at regular intervals and attain a new release level (for example, the IDoc
type SHPMNT has five instances, SHPMNT01 to SHPMNT05). Therefore, agree
with your EDI or IDoc partner on the release level that you will use, as well as the
IDoc type and EDI output. In our example, we choose the SHPMENT01 IDoc type.
Select the Basic type radio button and start the transaction by clicking on the
icon. The system then displays the parent segment E1EDK31 (see Figure 16.8).
