The column "Comp." for component indicates the assignment for the respective interface component.

Many segments of the interface IDocs have received segment expansions for Release 4.0. These are upwards compatible as far as the release status of the IDocs is explicitly defined as in the partner agreement. If you intend to continue working with the 3.0 segment definitions for data transfers to/from the external system, you need to also include the release status 3.0a in the partner agreement.

The IDocs WMTCID02 and WMMBID02 are assigned to the same message type. If you want to work with these IDocs, you need to simply replace the old IDoc names with the new ones in the partner agreement. Additionally, the segment E2LTCOH was changed when confirming IDocs; this means, you need to also append the release status in the partner agreement: 3.0a for the "old" version and 4.0a for the new segment.
