You can use the ITravelExpenseEnhancement interface to display customer-specific short texts for receipts in the receipt data entry area of Travel Expense. These customer-specific texts can be used to provide users with default short texts – based on expense type – for receipts.

If you display customer-specific short texts for receipts in the receipt data entry area of Travel Expense, you can also use SAP enhancement EX_BTEXT (Include MP56TFEX) to implement the enhancement in SAP R/3. This, however, is not mandatory.

You want to default the short text of receipts to "Custom default text". Proceed as follows:

1. Define a separate class, ZTravelExpenseEnhancement. This class must implement the ITravelExpenseEnhancement interface.
2. Implement the customizeRecord method. Use this method to define the default short text for the receipts if strOperation equals OP_RECEIPT_SET_DEFAULT.
