SAP系統(tǒng)變量用法----ABAP程序系統(tǒng)字段中英文詳解

1、SAP系統(tǒng)變量用法ABAP程序系統(tǒng)字段中英文詳解更新時(shí)間：2015-04-05 09:40:39編輯：SAP中文學(xué)習(xí)網(wǎng)點(diǎn)擊：55 發(fā)表評(píng)論 本文標(biāo)簽：系統(tǒng)字段變量SY-SUBRC: 系統(tǒng)執(zhí)行某指令后,表示執(zhí)行成功與否的變量,0 表示成功SY-DBLNT: 被處理過(guò)的記錄的筆數(shù) SY-UNAME: 當(dāng)前使用者登入SAP的USERNAME;SY-DATUM: 當(dāng)前系統(tǒng)日期;SY-UZEIT: 當(dāng)前系統(tǒng)時(shí)間;SY-TCODE: 當(dāng)前執(zhí)行程序的Transaction codeSY-INDEX : 當(dāng)前LOOP循環(huán)過(guò)的次數(shù)SY-TABIX: 當(dāng)前處理的是internal table 的第幾筆SY-TMA

2、XL: Internal table的總筆數(shù)SY-SROWS: 屏幕總行數(shù);SY-SCOLS: 屏幕總列數(shù);SY-MANDT: 當(dāng)前系統(tǒng)編號(hào)(CLIENT NUMBER)SY-VLINE: 畫(huà)豎線SY-ULINE: 畫(huà)橫線SY-PAGNO: 當(dāng)前頁(yè)號(hào)SY-LINSZ: 當(dāng)前報(bào)表寬度SY-LINCT: 當(dāng)前報(bào)表長(zhǎng)度SPACE: 空字符串SY-LSIND: 列表索引頁(yè)SY-LISTI: 上一個(gè)列表的索引SY-LILLI: 絕對(duì)列表中選定行的行號(hào)SY-CUROW: 屏幕上的行SY-CUCOL: 光標(biāo)列SY-CPAGE: 列表的當(dāng)前顯示頁(yè)SY-STARO:真實(shí)行號(hào)SY-LISEL: 選擇行的內(nèi)容，長(zhǎng)度

3、為255SY-LINNO: 當(dāng)前行系統(tǒng)內(nèi)部有一個(gè)專門(mén)存放系統(tǒng)變量的結(jié)構(gòu)SYST,其中最常用的系統(tǒng)變量有:SY-SUBRC: 系統(tǒng)執(zhí)行某指令后,表示執(zhí)行成功與否的變量,0 表示成功SY-UNAME: 當(dāng)前使用者登入SAP的USERNAME;SY-DATUM: 當(dāng)前系統(tǒng)日期;SY-UZEIT: 當(dāng)前系統(tǒng)時(shí)間;SY-TCODE: 當(dāng)前執(zhí)行程序的Transaction codeSY-REPID: ABAP 程式名，目前的主程式SY-CPROG: ABAP 程式名SY-SYSID: R/3 系統(tǒng)，R/3 系統(tǒng)名稱SY-UCOMM:  畫(huà)面，PAI 驅(qū)動(dòng)的功能代碼,一般用來(lái)參照定義變量SY-IN

4、DEX : 當(dāng)前LOOP循環(huán)過(guò)的次數(shù)   READ TABLE it_po INDEX 1  此時(shí)變量值1SY-TABIX: 當(dāng)前處理的是internal table 的第幾筆下面說(shuō)下sy-index 和 sy-tabix的區(qū)別sy-index和sy-tabix都是系統(tǒng)字段，用來(lái)記錄循環(huán)的次數(shù)。sy-index 在DO.ENDDO循環(huán)里有效，而sy-tabix在loop at .endloop里有效。運(yùn)行下面的例子能更好的理解：DATA: BEGIN OF line,   col1 TYPE i,   col2 TYPE i,

5、0;  END OF line.DATA itab LIKE TABLE OF line WITH HEADER LINE.DO 30 TIMES. line-col1 = sy-index. line-col2 = sy-index * sy-index. APPEND line TO itab.ENDDO.LOOP AT itab . DO 2 TIMES.   WRITE: / 'sy-tabix:',sy-tabix,itab-col1,    'sy-index:'

6、;,sy-index,itab-col2. ENDDO.ENDLOOP.sy-dbcnt:Sy-dbcnt代表有多少條記錄被處理了例如:當(dāng)我們查詢記錄放入內(nèi)表,判斷內(nèi)表中是否有數(shù)據(jù)就可以用if sy-dbcnt = 0  MESSAGE s000.     STOP. ENDIF.sy-tfill:返回當(dāng)前內(nèi)表(Internal Table)內(nèi)的記錄數(shù)。但是要小心，那些字段隨各自的內(nèi)表(Internal Table)改變。例：如果你循環(huán)(Loop at)（讀?。﹊tab，sy-tfill返回itab的記錄數(shù)。如 果你在循環(huán)(Loop at)（讀

7、取）內(nèi)表(Internal Table)itab的內(nèi)部嵌套循環(huán)(Loop at)（讀?。﹥?nèi)表(Internal Table)jtab，sy-tfill返回的不再是itab的記錄數(shù)，而是jtab的！所以如果你需要使用itab的記錄數(shù)，請(qǐng)先把sy-tfill的 值傳遞給其它變量。無(wú)論如何，sy-tfill永遠(yuǎn)保存當(dāng)前的記錄數(shù)。例如記錄內(nèi)表記錄條數(shù)：DESCRIBE TABLE itab LINES sy-tfill.SY-TMAXL: Internal table的總筆數(shù)SY-SROWS: 屏幕總行數(shù);SY-SCOLS: 屏幕總列數(shù);SY-MANDT: 當(dāng)前系統(tǒng)編號(hào)(CLIENT NUMBER)S

9、   空字符sy-cucol     光標(biāo)列sy-cpage    列表的當(dāng)前顯示頁(yè)sy-staro     真實(shí)行號(hào)sy-lisel       選擇行的內(nèi)容，長(zhǎng)度為255sy-linno      當(dāng)前行SY-MANDT: 當(dāng)前系統(tǒng)編號(hào)(CLIENT NUMBER)SY-SLSET:  SY-SUBRC 的含義= FUNCTION MODULE (或RFC中) SY-SUBRC 的含義 = 使用SELECT語(yǔ)句選擇查詢： SY-SUBRC = 0: 至

10、少有一行數(shù)據(jù)，當(dāng)ENDSELECT語(yǔ)句執(zhí)行完，SY-DBCNT中保存著記錄的個(gè)數(shù)。 SY-SUBRC = 4: 沒(méi)有數(shù)據(jù)。 SY-SUBRC = 8: 只有使用“SELECT SINGLE FOR UPDATE”時(shí)才會(huì)有，              表示: WHERE條件指定的記錄不止一行，結(jié)果是沒(méi)有記錄被選中。  使用INSERT語(yǔ)句，向表中插入一行，必須注意INSERT的順序與表中字段的順序一致： SY-SUBRC = 0: 插入成功，SY-DBCNT包含了插入的行數(shù)，0或1。 SY-SUBRC = 4: 由于

11、有相同的KEY存在，所以插入失敗。  使用LOOP語(yǔ)句來(lái)遍歷一個(gè)內(nèi)表： SY-SUBRC = 0: 循環(huán)至少被執(zhí)行一次。 SY-SUBRC = 4: 循環(huán)沒(méi)有被執(zhí)行，可能是沒(méi)有數(shù)據(jù)，也可能是沒(méi)有符合條件的記錄。  使用DELETE語(yǔ)句來(lái)刪除一條記錄： SY-SUBRC = 0: 找到一行并刪除之，如果該表有不唯一主鍵，也就是有多條重復(fù)的記錄，則只刪除第一條記錄。 SY-SUBRC = 4: 沒(méi)有找到符合條件的記錄，也沒(méi)有刪除。  使用UPDATE語(yǔ)句來(lái)更新一條記錄： SY-SUBRC = 0: 找到記錄并更新，（如果有多條記錄呢？） SY-SUBRC = 4: 沒(méi)

12、有找到符合條件的記錄，也沒(méi)有更新。 ABAP程序系統(tǒng)字段中英文詳解注_華亭慧劍譯系統(tǒng)字段由ABAP運(yùn)行時(shí)環(huán)境填寫(xiě)，并且可以用來(lái)在ABAP程序中查詢系統(tǒng)狀態(tài)。除了一個(gè)例外（sy-repid），系統(tǒng)字段都是變量，但是它們都是只讀的。此外，更多程序執(zhí)行的重要信息通常都被丟棄。ABAP程序中的系統(tǒng)字段只在極少需要控制系統(tǒng)行為的時(shí)候才能被重寫(xiě)。System fields are filled by the ABAP runtime environment and can be used in an ABAP program to query system statuses. With one excep

13、tion (sy-repid), system fields are variables, but they should only be accessed on a read-only basis. Otherwise, important information for further program execution often gets lost. System fields in ABAP programs can only be overwritten in a few cases to control system behavior.對(duì)于例外的sy-repid，這個(gè)系統(tǒng)字段的數(shù)

14、據(jù)類型在ABAP字典的SYST結(jié)構(gòu)（6.10版以后）中定義，作為sy結(jié)構(gòu)（也可以用SYST來(lái)定位）的組件在ABAP程序中有示例。sy結(jié)構(gòu)在一個(gè)內(nèi)部會(huì)話期間內(nèi)只存在一次，并且在這個(gè)內(nèi)部會(huì)話期間內(nèi)被所有程序使用。下表列出了在ABAP程序中可以使用的系統(tǒng)字段。所有sy結(jié)構(gòu)的其他組件則或者在ABAP運(yùn)行時(shí)環(huán)境內(nèi)部使用或者已經(jīng)廢棄。With the exception of sy-repid, the data types of the system fields are defined in the ABAP Dictionary in the structure SYST (as of releas

15、e 6.10), and are instantiated in ABAP programs as components of the predefined structure sy, which can also be addressed using SYST. The structure sy exists only once in an internal session and is used by all programs of an internal session at the same time. The following table shows the system fiel

16、ds that can be used in ABAP programs.

Counting begins at 1. In non-Unicode systems, this position also correspond
