You want to replace the standard Input Help for WBS Elements with a customer-specific Input Help by adding an additional column.

To do this, proceed as follows:

1. Define a new class ZPicklistsWBS. This class must be implemented by Interface IPicklistCustomer.
2. Implement method getColumnId in class ZPicklistsWbs. In this method, define field POSID as the return value.
3. Implement method getPicklistValues in class ZPicklistsWbs. Define the customer-specific Input Help in this method.

package com.sap.expense.customer.examples;

import com.sap.expense.model.Employee;

import com.sap.expense.model.modules.IEmployee;

import com.sap.expense.model.modules.IPicklistUI;

import com.sap.expense.tools.DBHelper;

import com.sap.mycats.basics.tools.badi.*;

import com.sap.mycats.basics.customer.userInterface.IPicklistCustomer;

/** The following record mus be defined in the customer file
