函数POPUP_TO_SELECT_MONTH可以弹出月份输入框从而使程序界面变得更加友好，示例如下：REPORT ZPOPUPMONTH .SELECTION-SCREEN BEGIN OF BLOCK blk01.  PARAMETERS: p_monat TYPE ISELLIST-MONTH.SELECTION-SCREEN END OF BLOCK blk01.INITIAL

BAPI_TRANSACTION_COMMIT有个WAIT参数，它类似于更新数据库语句的COMMIT和COMMIT AND WAIT。当不对WAIT参数赋值或赋为空时COMMIT会异步执行，否则会同步执行。这样当有两个业务需要连续执行的时候，第二个业务依赖与第一个业务，那么第一个业务BAPI在调用之后其BAPI_TRANSACTION_COMMIT的WAIT参数应赋为‘X’，否则便不能保证第一个业

可以通过FM：CONVERSION_EXIT_IDATE_OUTPUT，CONVERSION_EXIT_LDATE_OUTPUT输出描述性的日期，如果这两个FM的输出格式不能满足要求可以通过transparent table T247来读到月份的不同语言的短描述和长描述，自己写个FM来输出符合自己要求的日期格式。另：检查日期的合法性FM:DATE_CHECK_PLAUSIBILITY
