在修改已经存在数据的表的字段的数据类型时,一般需要在se14中调整并**,有时甚至要点击解锁表格,并重新生成表格,此时如果是HANA的某些版本的系统就会存在以下问题:

This could be an internal error in the database, the database client or in the SAP kernel.

可以看到该表可以允许主键相同的多条数据插入,且的数据删除时会报错

This could be an internal error in the database, the database client or in the SAP kernel.

This could be an internal error in the database, the database client or in the SAP kernel.

底层database会认为这些主键相同的数据是一条数据。

如果你也遇到了类似的问题千万不要到se11下删除该表,这样会导致该表名无法再次**。

原因是该表的索引没有生成

This could be an internal error in the database, the database client or in the SAP kernel.

This could be an internal error in the database, the database client or in the SAP kernel.This could be an internal error in the database, the database client or in the SAP kernel.
This could be an internal error in the database, the database client or in the SAP kernel.


在SE11创建索引即可


This could be an internal error in the database, the database client or in the SAP kernel.
此时便可恢复正常
