Now SAP Asset Performance Management has introduced GraphQL based APIs for its strategy applications, which cater to complex and nested data objects, like Assessments, Evaluations, Recommendatons etc.
This gives APM customers the ability to select all the data their UI needs in single API request. Asset Performance Management is one of the early adopters of GraphQL in SAP and has built SAP UI5 based applications which are powered by GraphQL APIs in the backend.
