Issue in the Autosar generated code

Hello,

I have an autosar model that takes the input via Rte interface and when I generate a code I see that the model is generating extra global variables. I am using R2018b.

Instead of using this global generated Highlighted in red, I want to use this input parameter coming from Rte (tmpRead_1.is_VOLTAGE_MONITOR ) highligted in Blue.

to simplify I want to get rid of the global generated from model and use the model input coming from Rte.

one thing I tried is changing the interface packaging, but When I try to change the code interface packaging to reusable function I got the following error.

could anyone provide solution for this topics.

Thanks!
