The third tab of the project page will show you data on the recipient's suppliers or subcontractors under three conditions:
1) You have selected to "Collect supply chain data" on the program level
2) You have shared the project with the recipient (more info here)
3) The supplier has entered data on their suppliers from their end
If a supplier enters data into OMX on their subcontractors, those subcontractors will in turn be able to enter data about their subcontractors, and in turn, this chain can continue on and on all the way down the supply chain. Thus, if Company A is the Prime contractor and they have indicated that Company B is a supplier to one of their programs, then Company B will be able to enter information on their suppliers that are related to the project. Those suppliers, let's say Company C, D and E can in turn enter data about their suppliers. There is no limit to how far down you can go in the supply chain to gain better understanding of your supply chain.
All of this data will be rolled up to the top level so that Company A can see the full blown downstream effect of the project that they have done with Company B. This tool can give you incredible insight into the lower tiers of the supply chain including who is in the supply chain, what types of work is being done, contract values and domestic content numbers.
All details in the subcontractors tab can downloaded into an Excel file.
