一、造成错误的操作

在ECC端通过appended  structure修改数据源的抽取结构之后，将请求传到生产机。

二、错误造成的影响

ECC前段业务无法成功地将数据保存到后台表。

三、Runtime Errors

(一)   LOAD_TYPE_VERSION_MISMATCH：

The current ABAP program "SAPLMCEX" had to be terminated because one of the statements could not be executed at runtime.

The ABAP runtime system detected that the Dictionary-type "ZZ2LIS_02_ITM" changed during the flow of the transaction. As the type was already used in the old version and in the new type should be used in the same transaction in the new version, the transaction had to be cancelled to avoid inconsistencies.

(二)   TYPELOAD_NEW_VERSION

The current ABAP program "SAPLMCEX" had to be terminated because one of the statements could not be executed at runtime.

The data type "ZZ2LIS_02_ITM" was loaded from the database during the program run. However, a type of a newer version than the one requried was found here.

四、错误原因

数据源抽取结构已激活，向 QRFC 队列中更新数据的更新程序正在执行时，字典的数据类型发生改变，造成字典类型与程序buffer中的类型不一致。

五、解决方法以及教训

(一)   解决方法：将抽取结构恢复为更改之前版本，并重新传输请求

(二)   教训：选取无业务操作的时段，传输请求
