1 When it receives the customer number from portlet 1, it displays the details of the customer's savings account.

2 Column 1 includes just the ID field (the customer number) for sorting.

3 After entering their customer number, the shopper clicks the Buy it button to initiate the purchase.

4 Given a customer number, WBCSCUST will return information about that customer.

5 In the first step, the customer number is copied to a local variable (1).

6 If the customer number is not null, that is, the customer is already known, the left hand path is followed (2), and the customer data is retrieved from the customer registration service (3).

7 For example, when configuring the customer number (CUST_NO) transformation, I defined this attribute as Integer (Figure 3).

8 Further, it assumes that any individual entity has some enterprise-unique identifier that's part of the record, such as a customer number or SKU.

9 There are three different pieces of information you need from each line: the seven-digit customer number, the customer name, and the single character customer type.

10 If you edit the customer master record you must specify customer number and company code in order to access the screens containing company code data.

11 Later, you will wire this button to call the HATS web service to search for customer information for the customer number entered into the customerNumberInputTextField widget.

12 C/S mode has good manageability and stability, but cannot automatically adapt to variation of customer number.

13 Any individual entity has some enterprise-unique identifier that's part of the record (for example, a customer number or SKU).

14 In this sample, we will discover a BAPI called BAPI_CUSTOMER_GETDETAIL, which retrieves the details of a customer according to the provided customer number.

15 The ListCustomer stored procedure provides a list of eligible customers by customer name, customer number, and date of birth (see Figure 2).

16 Remember that the existing program WBCSCUST takes as input a customer number and returns information about the customer.

17 In this case, it would bring back information about customer number 123.

18 In Listing 14, an attempt to insert into the table fails due to a foreign key constraint violation (SQLSTATE 23503) on the customer number.

19 Then create a new input business object for BAPI and set the customer number in the properties of the input business object.

20 Figures 19 and 20 show an example of the EJB test where we entered 1 for the customer number and received Daniel as the first name.
