具體操作步驟：
1. 使用TCODE:SE11，選擇最後一項[加鎖對象]，輸入對象名稱(注意一定要以字母‘E’開頭，這是SAP內部規定的，如EZ_FI_CSTM_001)
2. 輸入名稱後，按新增，進入界面後輸入要加鎖的Table名，及加鎖類型(E:專用，累計；S:共享；X:專用，不累計)。
保存後，系統會自動產生兩個函數： ENQUEUE_EZ_FI_CSTM_001（加鎖）和 DEQUEUE_EZ_FI_CSTM_001（解鎖）。
3.然後在更改記錄前調用加鎖函數對記錄進行鎖定，在修改完成或退出修改後一定要對記錄進行解鎖。
輸入鎖定表：
輸入鎖定表的字段：
然後在程序裏調用：
PERFORM frm_unlock_0100 USING p_inv p_cntr p_doc_ty.
