关于new enhancement sap源程序里也给我们留了很多。

以下例句point 、section、spot说明这些知识点。

1.不管是point还是section 都是基于spot的，spot相当于一个增强的容器。

2.point创建后没有代码只有一个预留点：

ENHANCEMENT-POINT ZENH_POINT01 SPOTS ZENH_SPOT01 .

需要去实现：可以实现多个

ENHANCEMENT 1  ZENHC_IMP01.    "active versionwrite 'this is enhancement-point zenh_point01 implementation' .WRITE : /.ENDENHANCEMENT.ENHANCEMENT 1  ZENHC_IMP02.    "active versionwrite 'this is enhancement-point zenh_point02 implementation'.ENDENHANCEMENT.

3.section创建后是有代码的，代码在ENHANCEMENT-SECTION 和END-ENHANCEMENT-SECTION之间

ENHANCEMENT-SECTION ZENH_SECTION01 SPOTS ZENH_SPOT01 .WRITE /.WRITE 'thsi is enchancement-section'.WRITE /.END-ENHANCEMENT-SECTION.

如果需要实现时，创建实现代码会自动带出ENHANCEMENT-SECTION 和END-ENHANCEMENT-SECTION之间的代码然后做修改，这样就只执行实现的代码不执行原来的代码，可以创建多个实现，但是测试下来貌似只是执行第一个实现，这里面的话只会执行ZENHC_IMP01. 如果没有ZENHC_IMP01会执行ZENHC_IMP02，如果没有ZENHC_IMP01和ZENHC_IMP02的话会执行ZENHC_IMP03不会执行ZENHC_IMP04.

ENHANCEMENT 2  ZENHC_IMP01.    "active versionWRITE /.WRITE 'thsi is enchancement-section ZENHC_IMP01'.WRITE /.ENDENHANCEMENT.ENHANCEMENT 2  ZENHC_IMP02.    "active versionWRITE /.WRITE 'thsi is enchancement-section ZENHC_IMP02'.WRITE /.ENDENHANCEMENT.ENHANCEMENT 1  ZENHC_IMP03.    "active versionWRITE /.WRITE 'thsi is enchancement-section  ZENHC_IMP03'.WRITE /.ENDENHANCEMENT.ENHANCEMENT 1  ZENHC_IMP04.    "active versionWRITE /.WRITE 'thsi is enchancement-section ZENHC_IMP04  '.WRITE /.ENDENHANCEMENT.

 下图表示创建定义point和sction的步骤，

创建增强实现如下图：

特别说明：创建的实现增强，可以在另外的point或者section中继续实现，如下图，zence_imp01在zenh_point01中实现过，在ZENH_SECTION01 中还可以继续实现，只不过

ID累加位2，如果在section中只会执行ID最高的实现。如果下面enchencement 2 zenhc_imp01  还有enchencement 2 zenhc_imp02 或者enchencement 1 zenhc_imp03，也只会执行enchencement 2 zenhc_imp01 。 

ENHANCEMENT 1  ZENHC_IMP01.    "active versionwrite 'this is enhancement-point zenh_point01 implementation' .WRITE : /.ENDENHANCEMENT.

ENHANCEMENT 2  ZENHC_IMP01.    "active versionWRITE /.WRITE 'thsi is enchancement-section ZENHC_IMP01'.WRITE /.ENDENHANCEMENT.

关于point和sction的static 测试下来没有发现特别的。
