You want to replace the standard Input Help for currencies with a customer-specific Input Help by hiding a column.

To do this, proceed as follows:

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

package com.sap.expense.customer.examples;

import com.sap.expense.tools.DBHelper;

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

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

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

* C:\me\wwwroot\te_customer\extensions\ci_records.xml

* <record name="ZPICKLIST_CURRENCY">

* <fields>

* <field name="F_CURRENCY" type="E_F_CURRENCY"/>

* <field name="CURRTXT" type="E_CURRTXT"/>

* <field name="RATE" type="E_RATE"/>

* </fields>

* </record>
