错误详细描述： An exception occurred that is explained in detail below.

The exception, which is assigned to class 'CX_SY_READ_SRC_LINE_TOO_LONG', was

not caught in

procedure "K_KKB_FIELDCAT_MERGE" "(FUNCTION)", nor was it propagated by a

RAISING clause.

Since the caller of the procedure could not have anticipated that the

exception would occur, the current program is terminated.

The reason for the exception is:

There was an attempt to read program "Z1S01R001" from the database.

The READ REPORT statement allows you to copy a program text into an

internal table. The occupied line length in the program text must not

exceed the width of the internal table.

The internal table "\FUNCTION=K_KKB_FIELDCAT_MERGE\DATA=L_ABAP_SOURCE[]" is 72

characters wide. The program line is 93 characters wide。

今天写个ABAP程序，一运行就荡掉，刚开始也没仔细看出错提示，以为是自己的代码写的问题，最后才搞懂，唉，原来是SAP系统不允许书写的代码长度超过72个字符，我的注释行的字符数太多了，导致了荡掉，唉，把长度很长的代码行，包括注释行，都变成72个字符以内后，就OK啦。
