Hi

In ABAP for each and every table there will be one communication structure which will start with MC.For ex if we r extracting the LO data , In the data source(2LIS_11_VAHDR) if we r not satisfy with the fields in the extract srtucture we use to move the fields from the communication structure(i.e MCVBAK,MCVBUK) to extract structure.IF the field is not available in the communication structure also then we will go for data source enhancement.

Communication Structure:

The communication structure is the structure of the InfoSource. It contains all of the InfoObjects belonging to the InfoSource .

Use:

The Data is updated in the data targets of this structure. In this way, the system always accesses the actively saved version of the communication structure.

In Logistic datasources maintaince time we need to move the fileds from communication Struc to Extract structure.

If you want to add the newfiled then you can add to extract structure.

hi,

An InfoSource is a quantity of InfoObjects that belong together and that contain all available information for a business process (for example,cost center accounting). The structure in which these are stored is called a communication structure. The communication structure is the technical realization of the InfoSource.The communication structure is, in contrast to the transfer structure, dependent on the source system, because the

communication structure can be supplied from different source systems.
