In this scenario, specific IMDS Users at the Tier 0 company have been granted “Trust User”
access into the company at Tier 2, but no IMDS users at the Tier 1 company enjoy Trust User
access into the company at Tier 2. The Tier 2 MDS contains confidential substances. When a
Tier1 user establishes their own MDS and references the received MDS of Tier2, The Tier 1
company cannot see Tier2’s confidential substances in the MDS, because no access is granted.
After Tier 0 receives the Tier1 MDS, Tier 0 can see the confidential data in the sub-tree
(referenced MDS) of Tier2, because tier2 granted access to the user of Tier 0.
In other words, once your company grants “Trust User” access to IMDS users of a company,
those trusted users see the confidential substances in all your MDSs – regardless of whether
the MDS has been sent directly, or indirectly as a reference in another supplier’s MDS. This also
applies for published MDSs. This scenario applies everywhere in the supply chain, even
through a chain of several business partners (here only 3), at the end of the chain (car
manufacturer as last element) and at the beginning (raw material producers as first element).
Note: The IMDS Company Administrator of an MDS creating company decides whether
any IMDS users at other companies can see confidential substances in their materials.
4.3 MDS Request
The IMDS MDS Send and Propose functions both begin with a supplier transmitting an MDS
to a customer. The MDS Request function is a mechanism by which a customer sends a request
for an MDS to a supplier. Before using MDS Request, the customer and their suppliers must
establish a dialogue outside of the IMDS system to agree the MDS Request function will be
used to communicate requirements and to identify the lead supplier to whom Requests will be
sent. This section details how to use the MDS Request function.
4.3.1 Parts of a Request
A Request tells a supplier which attributes the MDS must have (mandatory) and the
expected value of select attributes.
The Request itself consists of:
 A set of mandatory MDS attributes (base and recipient-specific)
