it might be of interest for you that there is a <b>MDM4A</b> Interface available in <b>SP04</b>.
The API allows direct access from any SAP system <b>(6.40/700)</b> to <b>MDM Server (SP04)</b>. This includes both <b>console like functions</b> and <b>Create-, Updated-, Retrieve-, Delete-, Client system keys- and Query functions</b> etc.
The API documentation includes a detailed interface documentation as well as 15 easy to understand How-to-Guides (https://websmp103.sap-ag.de/instguidesNW2004s -> SAP NetWeaver -> Release 04 -> Planning -> SAP MDM -> Documentation Center -> Operations).
If requested we could provide a recorded WebEx Demo. And last but not least we have RKT learning material (https://websmp207.sap-ag.de/~sapidb/011000358700003471552005E/R_NW04SCONSMDC.htm).
