Triggering referenced models in Simulink

I try to trigger a referenced model but I get the following error message: "Model" has multiple sample times. Only constant (inf) or inherited (-1) sample times are allowed in function call subsystem.

From what I've read triggered blocks must have inhereted solve time (-1). After setting the sample time of referenced model to (-1) I get the following error message:

Invalid FixedStep specified in the Configuration Parameters dialog for block diagram

Is there any documentation that can guide me to proper implementation of triggered models?

See "Triggered Sample Time" in: https://www.mathworks.com/help/simulink/ug/types-of-sample-time.html

See "Conditions for Inheriting Sample Times" in: https://www.mathworks.com/help/simulink/ug/inherit-sample-times-for-model-referencing-1.html

Thank you, you helped me find the answer.

In Configuration Parameters/Solver I had to set the Periodic sample time constraint to "Ensure sample time independent"
