This segment type is used to establish the connection between the SD data of a document item and the configuration data.

Segment E1CUREF is a sub-segment of segment E1EDP01, which contains the general item data such as quantity, unit of measure, item category, and so on.

Since configuration data is stored separately from the document item data, this segment is the interface between the two segments. It ensures that the correct configuration data is assigned to an item.

This segment contains the following fields:

POSEX

The external item number is used to identify the configuration data for a document item. The external item number is copied from the purchase order to the Purchase order item field in the purchasing data in the sales order. This means that the sales order item is assigned to exactly one purchase order item.

The value in this field must match the value in field POSEX in segment E1EDP01.

CONFIG_ID

The configuration data is identified by the CONFIG_ID.

INST_ID

The configurable material of the document item is identified by the INST_ID.
