在DateNavigator上設置分類

Question

我的朋友似乎在使用ABAP時遇到了一些麻煩。以下是他的問題的副本 - 張貼在SAP社區論壇上。

嘿大家， 我想有兩個類別，以紀念DateNavigator。我創建了一個名爲標記的上下文，其中包含日期，類別和工具提示。

節點：標記

• 日期：
• 類別：
• 工具提示：

我填寫類別屬性有兩類：e_category-three和e_category-four。我用Date來填充Date屬性。我希望這些日期中的一些是三類和其他四類。

當前，所有日期都設置爲第一類（e_category-three），代碼如下所示。

if ls_host_name-host_name <> host_msg and ls_vm_name-vm_name = vm_msg. 
    loop at lt_machine_booking into wa. 
    if ls_host_name-host_name = wa-host_name. 
     date = wa-reserved_from. 
     while date <= wa-reserved_till. 
     ls_dates_shared-dates = date.  > i want these dates to be e_category-three 
     append ls_dates_shared to lt_dates_shared. 
     add 1 to date. 
     ENDWHILE. 
    endif. 
    ENDLOOP. 
elseif ls_host_name-host_name <> host_msg and ls_vm_name-vm_name <> vm_msg. 
    loop at lt_machine_booking into wa. 
     if ls_host_name-host_name = wa-host_name and ls_vm_name-vm_name = wa-vm_name. 
     date = wa-reserved_from. 
     while date <= wa-reserved_till. 
      ls_dates_shared = date.  > i want these dates to be e_category-four 
      append ls_dates_shared to lt_dates_shared. 
      add 1 to date. 
     ENDWHILE. 
     endif. 
     " ...

我假設ls_dates_shared是標記類型？

如果是這種情況，您必須明確填寫字段ls_dates_shared-category和ls_dates_shared-tooltip。

目前這可能是代碼之前充滿片斷，你給我們。嘗試是這樣的：

if ls_host_name-host_name <> host_msg and ls_vm_name-vm_name = vm_msg. 
    loop at lt_machine_booking into wa. 
    if ls_host_name-host_name = wa-host_name. 
     date = wa-reserved_from. 
     while date <= wa-reserved_till. 
     ls_dates_shared-dates = date.  "i want these dates to be e_category-three" 
     ls_dates_shared-category = e_category-three. 
     "ls_dates-tooltip = appropriate_tooltip for e_category-three" 
     append ls_dates_shared to lt_dates_shared. 
     add 1 to date. 
     ENDWHILE. 
    endif. 
    ENDLOOP. 

elseif ls_host_name-host_name <> host_msg and ls_vm_name-vm_name <> vm_msg. 
    loop at lt_machine_booking into wa. 
    if ls_host_name-host_name = wa-host_name and ls_vm_name-vm_name = wa-vm_name. 
     date = wa-reserved_from. 
     while date <= wa-reserved_till. 
     ls_dates_shared = date.  "i want these dates to be e_category-four" 
     ls_dates_shared-category = e_category-four. 
     "ls_dates-tooltip = appropriate_tooltip for e_category-four" 
     append ls_dates_shared to lt_dates_shared. 
     add 1 to date. 
     ENDWHILE. 
    endif.
