本文对比了BI3.5与BI7.0环境下ABAP编程的不同之处，特别是内部表定义与读取的变化，并介绍了数据包的使用及循环语句的应用。此外还提到了转换规则、DTP集成及调试技巧。
In BI 7.0 environment, transformation (formerly called Update/Transfer rules) requires object oriented ABAP and here are some difference worth noting down between Object oriented ABAP and ABAP which would help you in working with BI 7.0.

|
BI 3.5 |
BI 7.0 |
|
Internal Table |
DATA: BEGIN OF INT_EBELN OCCURS 0, |
It's 2 step process in BI 7.0. 1st step declare the structure and in 2nd step declare Internal table referring to the above structure |
|
Reading data from Internal Table |
READ TABLE INT_EBELN INTO WA_PO WITH KEY |
1st define a Work area and read from there. |
|
Data Package |
|
Data: DATA_PACKAGE type table of _ty_s_SC_1, |
|
Loop Statement |
LOOP AT DATA_PACKAGE. |
LOOP AT DATA_PACKAGE INTO WA_DATA_PACKAGE |
Some points for consideration
1) We need to familiarize ourselves with transformation as well as DTP and the integration of both in the process chain. These are dependent once we perform data loads in production.
2) Check the validity of the routines generated from the auto transformation. You may also want to improve the existing routines or the overall transformation flow as well.
3) To debug a transformation routines you can use DTP (Tab: Execute >processing mode> serially in the Dialog Process (for debugging).
And Finally, Below is a very useful link from SAP BI help library which describes in a step-by-step how to migrate your data flow to the new concept (transformations and DTP's):
