Master Data IDocs

Maximal IDocs

A maximal IDoc specified by SAP contains all the information required for distributing an object. The structure is similar to the SAP system table structure.

Creating a Reduced IDoc

A reduced IDoc can be created from a maximal IDoc.

The structure of the IDoc is displayed in one of the transactions started from ALE Customizing. You can deactivate segments and fields. Mandatory fields cannot be reduced.

When a reduced IDoc is created from a maximal IDoc, a new message type is created and assigned to this IDoc. The reference to the message type of the maximal IDoc stays the same (for example, the new message type for material is MATSMD and the reference message type is MATMAS.)

This IDoc with the new message type is now used to transfer data rather than the maximal IDoc. It is automatically assigned to the change documents.

When sending IDocs of type MATMAS02, the E1MKALM segments (production version) are filled and sent, but are ignored by the receiving SAP system. This data may be used by non-SAP systems without any restrictions.

If short texts or long texts belonging to master data are changed, they are distributed and posted in the receiving system. Deleted texts are not transferred.
