在WEB DYNPRO ABAP中日期有默认的输入帮助，但时间只是u201CHH:MM:SSu201D的文本输入框。
写了一个ABAP Dictionary Search Help来处理
SEARCH HELP: Z_SH_TIME
SERCH HELP EXIT: ZTIME_SHLP_EXIT
PARAMETER: TIME_CHAR 类型 UZEIT
ZTIME_SHLP_EXIT中代码如下：
FUNCTION ztime_shlp_exit.
*"----
""Local Interface:
*" TABLES
*" SHLP_TAB TYPE SHLP_DESCT
*" RECORD_TAB STRUCTURE SEAHLPRES
*" CHANGING
*" REFERENCE(SHLP) TYPE SHLP_DESCR

EXIT immediately, if you do not want to handle this step
