2685	Connector with record fails with code generation issues	Adrian Pop	Mahder Alemseged Gebremedhin	"Hello everyone,

working on some controller model omc fails to reduce the variables using pantelides.

The error log is:
Error: Too many equations - overconstrained system. The model has 8 equations and 4 variables.
Error: Transformation Module PFPlusExt index Reduction Method Pantelides failed!

Find attached an examplemodel.
Unfortunately it is a bit complex therefore here is a short description.

A Record (with integer for value and enumeration for datatype)is used as connector (input and output).

within a block the value of the input changes to the output using an algorithm (simplification is done here!).

If you need further information with the model, let me know.
