Transfer of External Procurement Orders with CDP Data to SAP ERP 
The Characteristics-Dependent Planning (CDP) data at external procurement orders are stored as configuration data for purchase requisitions and purchase orders in SAP ERP.
As of ECC 5.0, a prerequisite for the integration of CDP characteristics for external procurement orders is SAP ERP Plug-In 2004.1.
If you want to use reference characteristics in Purchasing, you require ECC-DIMP 5.00 or higher and SAP ERP Plug-In 2004.1.
In external procurement orders, only value assignments of output nodes are transferred to SAP ERP. Characteristics of subcontracting components are not transferred.
You can create purchase requisitions with own configuration (as opposed to the planned orders in in-house production orders).
There may be an external procurement of a configurable material or of a material variant with a value assignment in stock that varies from the material master (but not with in-house production orders). For referencing or inheritance, the same rules apply as for in-house production orders.
CDP characteristic value assignments to purchase requisitions are stored in the purchase requisitions in SAP ERP as (own) configuration.
CDP characteristic values transferred from SAP APO cannot be changed in SAP ERP.
If you do not use DIMP, you can use the following functions:
You can use CDP in the make-to-stock segment in SAP APO by removing the configuration of orders before their transfer to SAP ERP.
You can restrict the orders per location and ATP category before the configuration is removed.
If you do not use DIMP, you can do the following:
