本文介绍如何通过SM30配置SSM_CUST以实现菜单项的精简及去除重复事务代码等功能。只需简单几步即可完成设置。

1、sm30
2、选择 “表/视图”： “SSM_CUST”，点击“维护”
3、点击 “新条目”，添加“CONDENSE_MENU ：YES ”
“ DELETE_DOUBLE_TCODES：YES ”
“ SORT_USER_MENU：NO”
4、保存即可生效

一般只需要 CONDENSE_MENU ：YES 即可

1.TECODE:se16n 打开需要更改的表并输入：/H 点击执行进入调试页面 2.修改变量：GD-EDIT 3.此时就可修改和删除表中数据了
飞凌全志T527开发板U-Boot添加自定义菜单

那现在可以回答第一个问题，如何做到按下按键后，是自启动U-Boot菜单，而不是进入U-Boot命令行呢？相信大家都试过，在U-Boot倒数结束前按任意按键后，会进入U-Boot命令行模式。解析到这里，我们得出一个结论：在autoboot倒计时中，如果有按键按下的话，会进入U-Boot的命令行模式。：是否重复（1重复，0不重复），指在U-Boot命令行按下Enter键的时候，重复执行上次的命令。至此，就实现了U-Boot倒数期间，有按键按下，则进入U-Boot的命令行模式。注意，这里的现象是直接启动内核，

SAP(ABAP)消除内表重复行记录 或者从数据表到内表进行SELECT后加distinct。 DATA IT_PRINT_001 LIKE 你的内表名 OCCURS 0 WITH HEADER LINE. IT_PRINT_001[] = 你的内表名[]. 排序： sort it_alv by liushui descending werks ps_psp_pnr ASCENDING. 删除掉重复内容： DELETE ADJACENT DUPLICATES FROM IT_PRINT_0.
SAP配置角色时，用户菜单出现重复Tcode

参考SAP NOTE 504006 - PFCG: New functions, corrections for role menu maintenance。设置CONDENSE_MENU_PFCG = YES。该步骤会生成TR，需在开发机配置后，传输至生产。SM30 ->编辑 SSM_CUST。

<br /> <br />在SAP系统中的系统表数据一般是不能手动直接添加、删除，所以在系统中会有一个标记字段记录。这里讲物料号的删除。<br />T-CODE：MM06   归档T_code: SARA  其它删除如销售伙伴（VD06）等都差不多。<br />删除标记：可以对物料在不同层次级别上进行删除标记. 它与归档不同，删除标记后是可以改变的，而归档是对物料进行彻底的删除，归档以后将不可用，相当于在数据内存中将数据记录进行删除.<br /><br /><br /><br />编辑---》选择开关<br
