We have a 3 tier PO landscape Dev -> QA -> Prod
I have created 3 technical systems TS_Test_Dev, TS_Test_QA and TS_Test_Prod in the SLD
In the past I have assigned the associated Product and associated Software component to all 3 technical systems.
Is this required though or can you just assign to the Dev technical system - in other words is this link only needed for design time?
