Mex file s-function does not support multiple rates

I have built a model into s-function (.mex64). The model used to work pretty well, however running the s-function gives me error message as below:

The S-Function block xxx/xxx/xx S-Function' has multiple rates, yet accesses the global data store 'mcae_pccr_v_mode'; S-Functions accessing global data stores must be single rate.

My model is a multi-rate model. Is it allowed to generate s-function?
