History
| Version | Date | Name | Description |
|---|---|---|---|
| V001 | 2020/10/8 | Huang Roy | 初版 |
| V002 | 2020/10/22 | Huang Roy | Add Method: GET_SHOW_MSG_STR |
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_STATIC_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_static_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_static_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。
- 如果沒有Raising指定exception作為通道，在實際執行時會直接short dump
