REST API via customized Representation and Classes get Error 404

Question

I planned to make a REST API through a new representation and class both named 'ZGACCENTRYA' based on the data source of GACCENTRYA. 
 My main objective is for the REST API able to call out the value of 'DIE' and 'CCE' with multiple dimensions via Postman but it turns out with the result as shown below. 
 
 And I check back my setting in Representation and did the global validation, the error triggered is shown in the diagram below. 
 
 I have tried to do research bout the error related, and some websites did explain what's the general issue of it but didn't show the solution to solve it. 
 The diagram below will show my settings of 'Representation' and 'Classes' of Z GACCENTRYA 
 
 Representation Setting:

Class Setting:

So what should I do to solve the error shown in Representation global validation?

Good day, 
 Update the datatypes used on your class definition to "Simple" data types ("A","DCB","C","L","M"). You are currently using "Reference" datatypes ("LED", "CPY", "FCY", "GTE", "VCR","GAC","DIE", "COA", "CCE",.....) which require refence links to variables which are not be part of your class definition. You do not require the enhanced scope as you simply want to use the REST service to "pull" data. 
 Once you have updated your class definition, perform a full validation of both the Class and Representation definitions. You will now be able to read data using the REST API.
