SAP-ABAP-搜索帮助，及搜索帮助出⼝1.创建搜索帮助
2.使⽤说明
2.1选择⽅法：指定搜索帮助表数据来源
2.2对话类型
2.2.1根据值集合的对话：如果数据量⼤于100条就不会直接展⽰数据，会先展⽰⼀个筛选界⾯
2.2.2⽴即显⽰值：就是⽴即展⽰数据源表中的全部数据
2.2.3具有值限制的对话：搜索帮助⼀开始不会将数据表中的全部数据展⽰出了，会给个筛选条件
2.3输⼊字段的建议搜索帮助：如果勾选该字段则不需要调⽤搜索帮助，在输⼊字段中直接输⼊与该字段同名的搜索帮助的输⼊参数的值，系统会根据你输⼊的内容在下⽅显⽰筛选结果.如果数据量⼤，或者搜索帮助附加字段太多了不建议使⽤
2.4多列全⽂搜索；容错全⽂本搜索的精确值
excel插入图片不使⽤搜索，⽽使⽤输⼊时，会将输⼊的数据按照字符串搜索表数据，按照搜索的精确值来显⽰最终数据。不建议使⽤，⽐较影响运⾏速度
2.5搜索帮助出⼝：可在创建的function中写⼊代码控制搜索帮助的数据。后⾯详细说明
2.6搜索帮助参数：展⽰出来的数据有哪些字段
2.7 IMP : 导⼊参量，⽤这些参量，从输⼊模板或处理屏幕的模板池中得到的值能复制给输⼊帮助处理。
2.8 EXP: 导出参量，⽤这些参量，从输⼊帮助处理得到的值能返回给输⼊模板。
2.9列表：该参数字段在命中列表的位置
2.10选择：该字段在选择屏幕中位置
2.11 选择：该参数的内容将告知⽤户该限制，但是⽆法更改该限制，这是可取的例如当该参数是导⼊参数或它有⼀个默认值。
2.12数据元素：参数字段对应的数据元素，必输
2.13已修改：如果⼀开始的搜索帮助变更了，此处勾会勾上，与使⽤⽤户⽆关
2.14缺省值：控制数据的默认值，默认值只能输⼊三种类型，a系统参数，如SY-DATUM;b内存get参数，如公司代码的内存参数BUK；c真正的默认值，需要⽤单引号包起来。
3.搜索帮助出⼝,SE37复制function--F4IF_SHLP_EXIT_EXAMPLE。注意命名和函数组，函数组要⽤Z开头的函数组，复制出来的名字建议按照ZFI_SH_CAR_TYPE_F4_EXIT类似命名，否则可能不让修改
异地医保怎么办理
复制完成的搜索帮助不会控制任何东西，在选择⼀次搜索帮助时会调⽤四次出⼝，⽤参数CALLCONTROL-STEP来控制是第⼏次
第⼀次：CALLCONTROL-STEP = 'SELONE'.
第⼀次的调⽤仅⽤于复合搜索帮助，在这次调⽤中它可以被使⽤以减少在SHLP_TAB中给出的基本搜索帮助的数量。
第⼆次：CALLCONTROL-STEP = 'PRESEL'.
第⼆次的调⽤我们可以修改⼀下限制条件，或者为了完全跳过对话框。
第三次：CALLCONTROL-STEP = 'SELECT'.
如何隐藏桌面图标这⼀步可以⽤来完全取代数据选择。
第四次：CALLCONTROL-STEP = 'DISP'.
第四次调⽤之后前台将展⽰表RECORD_TAB的数据，我们可以在这次调⽤中增减这个表的数据来影响最终展⽰数据

*"----------------------------------------------------------------------
* STEP SELONE (Select one of the elementary archhelps)
*"----------------------------------------------------------------------
* This step is only called for collective archhelps. It may be ud
* to reduce the amount of elementary archhelps given in SHLP_TAB.
* The compound archhelp is given in SHLP.
* If you do not change CALLCONTROL-STEP, the next step is the
* dialog, to lect one of the elementary archhelps.
* If you want to skip this dialog, you have to return the lected
* elementary archhelp in SHLP and to change CALLCONTROL-STEP to
* either to 'PRESEL' or to 'SELECT'.
IF callcontrol-step = 'SELONE'.
* PERFORM SELONE .........
EXIT.
ENDIF.
*"----------------------------------------------------------------------
* STEP PRESEL (Enter lection conditions)
*"----------------------------------------------------------------------
* This step allows you, to influence the lection conditions either
* before they are displayed or in order to skip the dialog completely.
* If you want to skip the dialog, you should change CALLCONTROL-STEP
* to 'SELECT'.
* Normaly only SHLP-SELOPT should be changed in this step.
IF callcontrol-step = 'PRESEL'.
* PERFORM PRESEL ..........
EXIT.
ENDIF.
*"----------------------------------------------------------------------
* STEP SELECT (Select values)

* This step may be ud to overtake the data lection completely.
* To skip the standard letion, you should return 'DISP' as following
* step in CALLCONTROL-STEP.
* Normally RECORD_TAB should be filled after this step.

ENDIF.
*"----------------------------------------------------------------------
* STEP DISP (Display values)
*"----------------------------------------------------------------------
* This step is called, before the lected data is displayed.
* You modify or reduce the data in RECORD_TAB
* according to the urs authority.
* If you want to get the standard display dialog afterwards, you
* should not change CALLCONTROL-STEP.
* If you want to overtake the dialog on you own, you must return
* the following values in CALLCONTROL-STEP:
* - "RETURN" if one line was lected. The lected line must be
* the only record left in RECORD_TAB. The corresponding fields of
* this line are entered into the screen.
* - "EXIT" if the values request should be aborted
* - "PRESEL" if you want to return to the lection dialog
* Standard function modules F4UT_PARAMETER_VALUE_GET and
* F4UT_PARAMETER_RESULTS_PUT may be very helpfull in this step.
