Simulink table port dimensions error

In the Simulink model that I'm developing, I'm using some Lookup Table Dynamic blocks. When I try to compile the model, the following message appears:

"Error reported by S-function 'sfix_look1_dyn' in '.../DLUT_manager/DLUT_pot1': Breakpoint and table port dimensions must be specified, they cannot be back-inherited. Recommendation: specify breakpoint port or table port dimensions using upstream blocks"

Where can I specify table port dimensions or breakpoint port?

Thank you

From the error, it appears that Simulink is unable to determine the dimensions of the 'xdat' and 'ydat' inputs to the Lookup Table Dynamic block. I would recommend inserting a Signal Specification block before each of the two inputs and specify their respective dimensions in the Signal Specification block dialog parameter "Dimensions".
