Secure Data Exchange

Not long ago I read an article about security issues that some companies are facing as they look to cloud services providers to replace their data services. These companies are just one configuration error away from exposing their company data to the world. This article made me think of the publish-subscribe architecture of Teamcenter Supplier Collaboration and how it provides secure data exchange.

With Supplier Collaboration, you can protect your data by assigning access rights to suppliers and to your designers (sponsors) who exchange data with them. Any OEM sponsor with the correct access rights can create an exchange package. However, before the package is sent to the supplier users, their access rights are also checked. Supplier users can get access by being members of projects, having company-wide access or having individual access rights.

If the OEM sponsor wants to allow a supplier user to change a sub-assembly, the sponsor must give the supplier user modification rights for the sub-assembly before sending the package. Modification rights can only be given when the supplier user has previously been given write access to the sub-assembly. The figure below describes a secure data exchange round trip.





In summary, in order for a supplier user to be able to download data these things must take place:

  1. The OEM sponsor must have the authority to share the data.
  2. The supplier user must have been given read access.
  3. The OEM sponsor must create the package and send it to the supplier.

And, in order for a supplier user to be able to send data back, these things must take place:

  1. The OEM sponsor must give the supplier user modification rights
  2. The supplier user must have been given write access.


So, you can see that with Supplier Collaboration’s secure data exchange it is very unlikely that you will accidentally expose your data to the world.

In addition to security benefits, Teamcenter Supplier Collaboration also offers integrated supplier business processes such as Design Data Exchange, Direct Materials Sourcing, and Supplier Program Management. Please check these links to our other blogs to give more background.



Nice faeature to give secured access to supplier for specific updates in material master but I hope that the access can be given to specific portion of master data update.  Eventhough, the core ERP system such as SAP has its own security layer where the data updates can be protected and tracked, still it is risky unless PLM has feature to slice it to what portion of access can be given further within sub-assembly part for example. If there will be an automatic update from PLM to ERP then we might end up in process failures in SAP in some cases such as triggering MRP run with wrong data for net requirements calculation and end up in triggering wrong replenishment etc.

With Supplier Collaboration, access rules for suppliers work the same as access rules for Teamcenter users. The rules can be applied anywhere in the item tree using ACL. When an assembly is shared with a supplier, the access rules are applied so that the supplier will only see parts or subassemblies to which they have read access.
