n We will consider the outbound order processing (enterprise trading company A is placing an

electronic order with vendor B) as well as the sales order (order being electronically processed by the

customer service department of vendor B).

n The course uses a sample IDoc type (ORDLGT01) for purchase orders and sales orders. This IDoc

type only consists of a segment for the document header and the item. The course does not correct

any errors in order to emphasize all important aspects of the IDoc type extensions.

n The IDoc type ORDLGT01 with logical message ORDLGT does not support transmission of

specialists name or delivery conditions. In this lesson, this information will be added to the IDoc

type.

n In the segment editor you assign a name to each field and enter a data element that describes the field

in the application (documentation). The editor calculates the necessary character length of the field in

the segment from the data element.

n Segment editor, transaction WE31.

n In the IDoc type editor you build a complex data structure from the single segments. In doing so the

order and the hierarchical relationships of the segments are documented. In addition, you assign a

status (optional/mandatory) as well as the number of repetitions per segment and segment group.

The IDoc API tests that the generated program (Outbound: SAP processing, inbound: subsystem)

conforms to these characteristics. Violations of these characteristics are recorded through the IDoc

status syntax error (Outbound: 26, inbound 60).

In the scenario send a purchase order to vendor T-BILQQ. In the second

step make the purchase order the sales order from customer T-BIKQQ.

In order to keep the exercises manageable, the IDoc type ORDLGT01 has been

introduced with message ORDLGT. This is a simplification of SAP standard

ORDERS01 and is only used for this course.

purchased for plant 1100.

A partner profile for your partner already exists. It ensures that the IDoc is written

in a file and thus receives the status 03.

1-2 You simulate the incoming orders via the LQERXQG(cid:3)PRGLILHG(cid:3)RXWERXQG(cid:3)ILOH test

program from the purchase order. You can offer default values for source,

destination and port by choosing *RWR(cid:3)fi(cid:3)8VHU(cid:3)VHWWLQJV and selecting the port

SUBSYSTEM for the test.

Enter the following values on the tab page 6HQGHU:

2-1 Extend the inbound processing of IDoc type ORDLGT01 to avoid errors status

“51”. Change the received error document type NB in one of the customer exits to

type.

• Get to know project management

• Be able to write the program code for outbound processing

In exercise 1 the field for 6SHFLDOLVW(cid:3)QDPH remained blank, even though it

was defined in the IDoc type. Since it has been agreed with your partner

to transfer the field, you decide to take care of the field through a

customer exit. There is no need to extend the IDoc type.

3-1 Change the 3URMHFW(cid:3)%&(cid:25)(cid:21)(cid:20)(cid:16)QQ in the project management (transaction CMOD) or

create it for the first time (if you have not completed exercise 2). Select the SAP

extension %&(cid:25)(cid:21)(cid:20)(QQ for the project. Write the program code in the extension

component for the outbound processing.

3-2 Activate your project.

generated from the overview screen by choosing 6\VWHP(cid:3)fi(cid:3)/LQNV. Check that the

field with the user name has now been filled .

• Know how to use IDoc type editor

Your IDoc type ORDLGT01 does not contain any fields in order to

transfer the document header delivery conditions. You have to extend the

data structure, that is, the IDoc type, since delivery conditions have been

agreed to with your partner.

4-1 First define the customer segment =(cid:20),1&2QQ in the segment editor. Customer

segment Z1INCOnn is to contain application fields INCO1 and INCO2. In the

application both fields INCO1 and INCO2 are contained in the structure EKKO.

4-2 In the segment editor, test that your definition is correct. Ignore the warning that the

segment has not yet been released.

4-3 Define the extension =(;7(1QQ(cid:3)in the IDoc type editor. Extend the basic IDoc

type ORDLGT01 by segment Z1INCOQQ.

4-4 Add to the logical message ORDLGT the basic type ORDLGT01 with the

extension ZEXTENQQ in the IDoc type editor.

4-5 In the IDoc type editor, test that your definition is correct. Ignore the warning that

the IDoc type as well as the segment Z1INCOQQ has not yet been released.
