Introduction

Class: ZCX_NO_CHECK

• Enhance Exception Class: CX_NO_CHECK
• Easy to trace exception

History

Version	Date	Name	Description
V001	2020/12/10	Huang Roy	初版

Class Screen

• Long Text: 設定如文章一般的超長訊息
• 左側為Text ID，右為Text

• 請 不要 修改此Exception Class，以繼承方式加上新的textid或是直接自訂訊息
• 繼承的Exception Class皆可以upcasting to ZCX_NO_CHECK
• Exception Class一定要是YCX_ or ZCX_ 開頭

RAISE Syntax

• textid未設定，預設是使用exception class同名text id
• msg1~msg4為自訂訊息，在text內可以用 &msgN& 作為變數附加訊息

RAISE EXCEPTION TYPE zcx_no_check
  EXPORTING
    textid = xx
    msg1   = xx
    msg2   = xx
    msg3   = xx
    msg4   = xx.

Public Method

SHOW

• 顯示錯誤訊息視窗(Background Job顯示於spool)

Parameter	Level	Pass Value	Optional	Type(Ref To)	Default	Description
I_LONG	Importing		X	ABAP_BOOL		Show Long Text

Sample 1: 使用textid(zcx_no_check=>no_data)

• 由於是static check，須在methods後加上RAISING語法，未加時check syntax會提示。
• 由於是no check，在method後不用加RAISING語法，但也由於是no check，所以check syntax時不會提醒需要catch的exception class。
