How to manage the regulatory data import into specification database?

Hi experts,

We have a EH&S implementation project for a distribution company which has no other sap module and very limited scope.

They want to get the 3E data, compare and update and send/updates with vendors and customers and also inteface the data with AS 400.

They are not willing to use the Ariel ADM tool and any other additional licensing, due to limited scope.The 3E is sending the file in xml format. So the EH&S OCC connector could be used. but this again needs the use of ehs expert, which needs additional licensing and scope increase.

Does anybody worked on intergrating 3E data into specifications without usig ADM and OCC?

Regards
