培训总结二

1 dev aleremote,参数文件S_BI-WX_RFCA，SAP_ALL

BW bwuser 参数文件：S_BI-WHM_RFC

2，sm51 yteccdev_DEV_01

3,WE21处理中的idoc,WE20合作伙伴参数

4，数据源是与源系统相关的。

5，rso2维护一般数据源

6，rsa3验证是否可以在源系统提取到数据

7，rsa6激活数通用的数据源

8，函数组RSAX复制出一个函数组，选择复制RSAX_BIW_GET_DATA_SIMPLE。

代码如下

function zrsax_biw_get_data_simple.

* Example: DataSource for table SFLIGHT

* TABLES: SFLIGHT.

tables: zcust.

* Auxiliary Selection criteria structure

data: l_s_select type srsc_s_select.

* Maximum number of lines for DB table

statics: s_s_if type srsc_s_if_simple,

* counter

s_counter_datapakid like sy-tabix,

* cursor

s_cursor type cursor.

* Select ranges

* RANGES: L_R_CARRID FOR SFLIGHT-CARRID,

* L_R_CONNID FOR SFLIGHT-CONNID.

9，标准数据源增强。使用badi的方式

RSU5_SAPI_BADI SE19

RSA6选择增强提取结构。增强字段以ZZ打头（经验证不需要）。

10 数据源增强后，默认为隐藏，需更改为显示。

11，当数据目标有数据时，数据源字段需删除数据后再修改结构。

12，lbwe，lo数据抽取。通讯接口增强。--见文档。
