(C4103) Subroutines containing parameters defined as a non-unique user-defined type

Error In:
Completeness
Description:
A parameter of a subroutine is defined as a user-defined type (UDT), whose name is not unique in the model.
Example:
DAYS, a parameter of function F1 is defined in terms of a UDT T_DAYS. This UDT is defined twice in the model and therefore is not unique.
Erroneous Elements:
