今天又学习了一下Idoc的知识，包括Idoc的概念、开发、配置和管理。
Concept
EDI：公司之间的电子数据交换。
ALE：公司之内不同系统之间的数据交换。
IDOC：基本上就是EDI的一种实现形式，用于SAP。

Control record, data record, status record
Outbound and inbound
Sender and receiver
Partner(协议) and port（发送的形式eg：File, RFC,XML）
Status

IDoc Development
Message type WE81, identifies type of data : MATMAS (material master)

Idoc type WE30, indicates the SAP format of the data : MATMAS05 ( 05-version)

Segment WE31, structures used to define data: E1MARAM (material master general data)
Link message type with basic type WE82

Outbound – outbound process code/outbound function module WE41, only for application outbound

Inbound – inbound process code/inbound function module WE42

Link inbound function module to message type and Idoc type WE57
Mtn. inbound function module attribute BD51

IDoc Configuration
General: RFC destination SM59，定义 transactional RFC port destination

Logical System BD54，定义LS partner type

Partner Profile WE20, 用于定义数据交换的参数

Port WE21，用于定义各类port

For Master data outb ： distribution model BD64

For Application data outb ：outb process code WE41
                                                          Condition type NACE
Demo: 1）master data outbound and inbound
从IDES 800 发到 IDES 810:
            1. develop idoc type in 800
            2. config destination LS/port/partner profile in 800
            3 config LS/partnerprofile in 810
            4. test with BD10
            5. check with WE02

Demo: 2) purchase order output to file
            1. use standard message type ORDERS，idoc type orders05，define process code（WE41）ME10
            2.config port, LS, partner profile; for application only : process code and condition type
            3. configure condition type(同义：message type, output type) : NACE 1output type 2procedure
            4.test with create PO
            5.check with WE02 , AL11 check directory

IDoc administration
Transactions:
WEDI: Area Menu

WE02/WE05: display Idoc

BD87: Monitor/process Idoc message

WE19: Test/Reprocess Idoc

Program:

RSNAST00: create idoc for message(application data)

RSEOUT00: process all selected Idocs (EDI)

RBDAPP01: Inbound Processing of Idocs ready for transfer
Tips:

Tables: EDIDC(control record : idoc)

EDID4: Idoc records from 4.0 onwards

EDIDS: status record

NAST: Message record (application data)

Function modules:

IDOC_WRITE_AND_START_INBOUND: create Idoc and process Idoc

MASTER_IDOC_DISTRIBUTE: create outbound Idoc
