Prior to MIING on the ENDEE approach transition tried to load MINNG approach transition into CDU while flying the ENDEE Arrival. Because MIING is a fix on the ENDEE arrival with two waypoints after MIING and MIING is the initial fix on the RNAV (RNP) Y 22L approach; there was confusion as to how to load the approach into the CDU. We kept getting a route discontinuity. Finally disconnected autopilot and flew approach manually. Approach Control eventually issued a visual approach clearance.[To prevent this confusion in the future flight crews should take] a detailed look at the construction of the arrival and 22L Y approach and perhaps [there should be] a bulletin calling attention the complexity of the arrival and approach. After speaking with Approach Control personnel; a procedure of using only the STERE transition of the 22L Y approach instead of the MIING transition was discussed. I have spoken with the Manager of ATC systems prior and will speak with him again today regarding this issue.
A B737NG flight crew flying the ENDEE RNAV STAR to MDW was unable to program the transition between MIING waypoint on the STAR and the RNAV approach to Runway 22L. They took manual control of the aircraft and completed the approach and landing.
