The Properties tab of the IDoc source definition displays the following information:

The Select and Order By options are not available for IDoc definitions.

In the Source Analyzer, you can import an entire IDoc or an individual segment of an IDoc. If two different IDocs have segments with the same name, you can edit the IDoc Type to indicate which segment you want to use in the mapping.

For example, the IDocs E1BPACAR01 and E1BPACAR02 both have a segment named E1MVKEM. You import E1MVKEM from E1BPACAR01 in the Source Analyzer. You cannot import E1MVKEM twice in the Source Analyzer. To use the E1MVKEM segment from E1BPACAR02, change the IDoc Type in the Mapping Designer to E1BPACAR02.
