• Lines 87-95: Fetch each of requisition's non full supply products from reference data service one by one.

Solutions

Both save and submit:

• Return only relevant information about a requisition to the client: Do we really need to return non full supply products in the response of those endpoint? Perhaps we could keep this as a set of UUIDs instead of calling orderableReferenceDataService.findOne for each one of them,

Submit:

• We could reuse products that were previously retrieved in RequisitionController. 
• Try not to fetch all the orderables, search them by program instead.
