In order to activate the customer enhancements such as those described in the examples with Java source code, you need to create a new class: com.sap.mycats.customer.ZenhancementProvider.
This class must implement the Interface IEnhancementProvider.

Use the following implementation to activate the customer enhancements implemented using Java interfaces:

package com.sap.mycats.basics.customer;

import com.sap.expense.customer.examples.*;

import com.sap.mycats.basics.customer.IEnhancementProvider;

import com.sap.mycats.basics.customer.IEnhancement;

public class ZEnhancementProvider implements IEnhancementProvider {

public IEnhancement[] getEnhancements () {

IEnhancement result[] = new IEnhancement[5];

result[0] = new ZPicklistWbs();

result[1] = new ZPicklistCurrency();

result[2] = new ZTravelExpenseEnhancement();

result[3] = new ZTravelExpenseService();

return result;

}

}
