Transformation Error of Composite Mapping Type when using "?"

I need some assistance.  The following error is displayed during the Load and Transform WF step (v9.0.1.17608): 

The use of "?" and "*" is discussed in the Design and Reference guide as per below:

Requirement:  There is an entity with 5 characters with suffix _ICI30 that needs to map to C4500 if the IC has 5 characters, and another with 9 characters with suffix _ICI30 that needs to map to C3000 if the IC has 5 characters.   

How do I define the rule expression if E#[?????_ICI30]:I#[?????]  and E#[?????????_ICI30]:I#[?????] are incorrect?
