PowerApps 的常見問題與解決方案Common issues and resolutions for PowerApps

最近新增/變更Recently added/changed

  1. 應用程式無法運作App won't work

    如果您建立的應用程式無預警地停止運作,原因可能是您在過去六個月內未更新或重新發佈該應用程式。If an app you created stops working without warning, it might be because you haven't updated or re-published it in the last six months. 若要解決此問題,請更新和/或重新發佈您的應用程式,以便和最新版本的 PowerApps 進行同步處理。然後,請務必在發佈應用程式後的六個月內繼續更新和/或重新發佈該應用程式。To resolve this issue, update and/or re-publish your app to sync it with the latest version of PowerApps, and then make sure that you continue to update and/or re-publish the app within six months of last publishing it.

  2. 資料表控制項Data Table control

    如果您複製並貼上某個資料表控制項,而其 Items 屬性設定為包含 Filter 函式的公式,則 Items 屬性的公式在新的資料表控制項上將會出現包含 _1 尾碼的欄位名稱。If you copy and paste a Data Table control for which the Items property is set to a formula that contains a Filter function, the formula for the Items property on the new Data Table control ends up with field names that contain a _1 suffix. 欄位名稱將因此而無效,且資料表將不會顯示任何資料。This makes the field names invalid and results in no data showing up in the data table. 若要解決此問題,在複製控制項之前,請確認 Filter 函式並未參考資料來源中任何與資料表控制項中的資料行同名的欄位。To work around this issue, before you copy the control, confirm that the Filter function doesn't reference any field in the data source that has the same name as a column in the Data Table control. 如果有此類參考,請重新命名資料表控制項中的資料行。If it does, rename the column in the Data Table control. 或者,請從無效的欄位名稱中移除 _1 尾碼,使這些名稱符合實體中的名稱。Alternatively, remove the _1 suffix from the invalid field names so they match the names in the entity.

  3. 適用於 Windows 的 PowerApps Studio 中的相機控制項Camera controls in PowerApps Studio for Windows

    如果您新增相機控制項或開啟使用相機控制項的應用程式,適用於 Windows 的 PowerApps Studio 可能會當機。PowerApps Studio for Windows may crash if you add a camera control or open an app that uses a camera control. 若要避免這個問題,請使用適用於 Web 的PowerApps Studio 來新增或使用相機控制項。To avoid this problem, use PowerApps Studio for web when adding or using a camera control.

  4. 在 Android 裝置上的 2.0.700 版Release 2.0.700 on Android devices

    若您在 Android 裝置上安裝 2.0.700 版,然後無法開啟應用程式 (或應用程式停止回應);請解除安裝 PowerApps、重新啟動裝置,然後重新安裝 PowerApps。If you install release 2.0.700 on an Android device and then can't open apps (or an app stops responding), uninstall PowerApps, restart the device, and then reinstall PowerApps.

  5. 開啟應用程式時,「清空」資源庫"Empty" gallery when opening an app

    如果是由資料自動產生應用程式,請儲存應用程式,並再重新開啟,瀏覽資源庫可能不會立即顯示任何資料。If you generate an app automatically from data, save the app, and then reopen it, the browse gallery might not immediately show any data. 若要解決此問題,請在搜尋方塊中輸入至少一個字元,然後刪除輸入的文字。To resolve this issue, type at least one character in the search box, and then delete the text that you typed. 資源庫就會如預期顯示資料。The gallery will then show data as expected.

  6. 升級 Windows 8.1 中的 PowerAppsUpgrading PowerApps on Windows 8.1

    如果您的 PowerApps 安裝在執行 Windows 8 或 Windows 8.1 的電腦中,請將 Windows 市集應用程式保持在開啟且作用中的狀態,再使用設定常用鍵檢查是否有更新,並安裝這些更新。If you install PowerApps on a computer that’s running Windows 8 or Windows 8.1, keep the Windows Store app open and active, use the Settings charm to check for updates, and then install them.

  7. 自訂連接器和 Common Data ServiceCustom connectors and the Common Data Service

    如果使用 PowerApps Build 2.0.540 或之前的版本建立的應用程式依賴 Common Data Service 中的資料庫,以及至少一個在不同環境中的自訂連接器,則需要將連接器部署到與資料庫相同的環境中,並更新應用程式以使用新的連接器。If an app created using PowerApps build 2.0.540 or earlier relies on a database in the Common Data Service and at least one custom connector in a different environment, you’ll need to deploy the connector to the same environment as the database and update the app to use the new connector. 否則,會出現對話方塊通知使用者找不到 API。Otherwise, a dialog box will notify users that the API was not found. 如需詳細資訊,請參閱環境概觀For more information, see the overview of environments.

  8. 在 Windows 8.1 中執行應用程式Running an app on Windows 8.1

    如果您安裝此適用於 Windows 8.1 的更新,您無法於該作業系統中執行在 PowerApps Studio 開啟的應用程式。If you install this update for Windows 8.1, you can't run apps that you open in PowerApps Studio on that operating system. 不過,您仍然可以執行在 powerapps.com 中開啟的應用程式,或使用 PowerApps Mobile 來執行。However, you can still run apps that you open in powerapps.com or using PowerApps Mobile.

  9. 包含空格的資料行名稱Column names with spaces

    如果您使用 SharePoint 清單或 Excel 資料表,其中的資料行名稱包含空格,PowerApps 會將它取代為 "_x0020_"If you're using a SharePoint list or an Excel table in which a column name contains a space, PowerApps will replace it with "_x0020_". 例如,SharePoint 或 Excel 中的 "Column Name" 在資料版面配置中顯示或是在公式中使用時,會在 PowerApps 中顯示為 "Column_x0020_Name"For example, "Column Name" in SharePoint or Excel will appear as "Column_x0020_Name" in PowerApps when displayed in the data layout or used in a formula.

舊版Older

  1. 變更共用應用程式中的流程Changing a flow in a shared app

    如果您將流程新增至應用程式、共用該流程,然後在該流程中新增服務或變更連線,您必須從共用應用程式中移除該流程,並再次新增流程,然後重新共用應用程式。If you add a flow to an app, share it, and then add a service or change a connection in the flow, you must remove the flow from the shared app, re-add the flow, and reshare the app. 否則,觸發該流程的使用者收到驗證失敗的訊息。Otherwise, users who trigger the flow will get an authentication failure.

  2. 使用當地語系化的版本Using a localized version.

    如果您在 Windows 8.1 中執行 2.0.531 版,且裝置設定為需要 IME 視窗的語言,您則無法在文字輸入控制項中輸入內容。If you're running release 2.0.531 on Windows 8.1, you can't type in a Text input control if the device is set to a language that requires an IME window.

  3. Windows Phone 上的相機控制項Camera control on a Windows Phone

    如果您在執行 Build 10.0.10586.107 的 Windows phone 中開啟包含相機控制項的應用程式,該應用程式可能會當機。An app that contains a camera control might crash if you open the app on a Windows Phone that's running build 10.0.10586.107. 若要避免這個問題,請升級為最新的 Build 版本 (例如,執行 Upgrade Advisor)。To avoid this problem, upgrade to the most recent build (for example, by running the Upgrade Advisor).

  4. 從範本開啟應用程式Opening an app from a template.

    如果您執行 2.0.500 或較舊版本,當您嘗試從範本建立應用程式時會出現錯誤訊息。If you're running release 2.0.500 or older, an error message appears when you try to create an app from a template. 您必須升級才能使用這項功能。You must upgrade to be able to use this feature.

    如果您執行 2.0.510 或更新版本,當您嘗試從範本建立應用程式時會出現警告。If you're running release 2.0.510 or later, an warning might appear when you try to create an app from a template. 儘管如此,您可以關閉訊息並建立應用程式。However, you can close the message and create the app.

  5. 掃描條碼Scanning a barcode

    如需使用條碼控制項之限制和最佳做法的相關資訊,請參閱掃描條碼For information about limitations and best practices when you use a Barcode control, see Scan a barcode.

  6. 在瀏覽器中建立及修改應用程式Creating and modifying apps in a browser

    在適用於 Web 的 PowerApps Studio 中您可以執行許多與適用於 Windows 的 PowerApps Studio 中相同的作業 (但非所有作業都相同)。You can do many, but not all, of the same things in PowerApps Studio for web as you can in PowerApps Studio for Windows. 如需詳細資訊,請參閱在瀏覽器中建立應用程式For more information, see Create an app in a browser.

  7. 變更實體中的標題欄位Changing a Title field in an entity

    如果您變更其他實體透過一或多個查閱參考之實體的 [標題] 欄位,在嘗試儲存變更時便會發生錯誤。If you change the Title field for an entity that other entities reference through one or more lookups, an error will occur when you try to save the change. 若要解決這個問題,請移除欲變更 [標題] 欄位之實體的任何查閱、進行變更,然後重新建立查閱。To work around this issue, remove any lookups to the entity for which you want to change the Title field, make the change, and then recreate the lookups. 如需查閱的詳細資訊,請參閱建立實體之間的關聯性For more information about lookups, see Build a relationship between entities.

  8. 連線內部部署 SharePoint 的應用程式Apps that connect to on-premises SharePoint

    如果您共用的應用程式需依賴未自動共用的連線 (如內部部署 SharePoint 網站),在瀏覽器中開啟應用程式的使用者會看到對話方塊,但是當他們按一下或點選 [登入] 時,該對話方塊將不顯示任何文字。If you share an app that relies on connections that aren’t automatically shared (for example, an on-premises SharePoint site), users who open the app in a browser will see a dialog box with no text when they click or tap Sign in. 若要關閉對話方塊,請按一下或點選右上角的關閉 (X) 圖示。To close the dialog box, click or tap the close (X) icon in the upper-right corner. 如果您在 PowerApps Studio 或 PowerApps Mobile 中開啟應用程式,該對話方塊不會出現。The dialog box doesn’t appear if you open the app in PowerApps Studio or PowerApps Mobile. 如需共用連線的詳細資訊,請參閱共用應用程式資源For more information about shared connections, see Share app resources.

  9. 當 PowerApps 從資料產生應用程式時,用來排序和搜尋的欄位無法自動設定When PowerApps generates an app from data, the field used for sorting and searching isn't automatically configured.

    若要設定此欄位,請編輯資源庫的 Items 公式,如新增資源庫中說明篩選和排序的一節所述。To configure this field, edit the Items formula for the gallery, as the sections for filtering and sorting in Add a gallery describe.

  10. 從資料建立的應用程式只能存取資料來源的前 500 筆記錄For apps that are created from data, only the first 500 records of a data source can be accessed.

    在一般情況下,PowerApps 能透過將作業委派給資料來源來搭配任何大小的資料來源。In general, PowerApps works with any size data source by delegating operations to the data source. 對於無法委派的作業,PowerApps 會在撰寫時提出警告,並只會針對資料來源的前 500 筆記錄發揮作用。For operations that can't be delegated, PowerApps will give a warning at authoring time and operate on only the first 500 records of the data source. 如需委派的詳細資料,請參閱 Filter 函式一文。See the Filter function article for more details about delegation.

  11. Excel 資料必須格式化為資料表Excel data must be formatted as a table.

    如需將 Excel 當做資料來源之限制的詳細資訊,請參閱雲端儲存體連線For information about limitations when you use Excel as a data source, see Cloud-storage connections.

  12. SharePoint 自訂清單可受支援,但資源庫、某些類型的清單資料行,或支援多個值或選擇的資料行則不受支援SharePoint custom lists are supported but not libraries, some types of list columns, or columns that support multiple values or selections.

    如需詳細資訊,請參閱 SharePoint OnlineFor more information, see SharePoint Online.

  13. 不支援共同撰寫。一次僅限一位作者Co-authoring isn't supported. One author at a time, please.

    如果多位人員同時修改同一個應用程式,可能會導致應用程式毀損或覆寫其他人員的變更。You can corrupt an app or over-write others’ changes if more than one person modifies the same app at the same time. 若要讓其他人員編輯應用程式,請先將它關閉。Close the app before someone else edits it.

  14. 新共用的應用程式有時候可能要經過一段時間後才能使用It can sometimes take a moment before a newly shared app can be used.

    在某些情況下,新共用的應用程式無法立即使用。In some cases, a newly shared app won't be immediately available. 稍待片刻後,應用程式就應該可供使用。Wait a few moments, and it should become available.

  15. 表單控制項中,您無法使用自訂卡片來變更資料In the Form control, you can't change data by using a custom card.

    庫存的自訂卡片缺少寫回變更所需的 Update 屬性。The stock custom card is missing the Update property, which is required to write back changes. 若要解決這個問題︰To work around this:

    • 選取表單控制項,並根據卡片應顯示的欄位使用右側窗格插入卡片。Select the form control, and insert a card by using the right-hand pane based on the field that you want the card to show.
    • 解除鎖定卡片,如了解資料卡片所述。Unlock the card, as described in Understanding data cards.
    • 視需要移除或重新排列卡片內的控制項,如同操作自訂卡片一樣。Remove or rearrange controls within the card as you see fit, just as you would with the custom card.
  16. 在安裝 Webview v48 或 v49 版之 Android 5.0,Nexus 6 上執行的應用程式可能會當機An app that's running on Android 5.0, Nexus 6 with Webview versions v48 or v49 may crash.

    若要修正這個問題,使用者可以將 Webview 更新為較低版本 (3x) 或將 Android 更新為 6.0。Users can fix this problem by updating to a lower version of Webview (3x) or update to Android 6.0.

  17. 如果記憶體不足,相機可能會暫時遭到停用Camera usage may be temporarily disabled if memory is low.

    如果行動裝置的記憶體不足,為了避免損毀裝置,相機會暫時遭到停用。If your mobile device is low on memory, the camera is temporarily disabled to avoid crashing the device.

  18. 不支援 Office 365 影片連接器Office 365 Video connector isn't supported.

  19. 卡片資源庫已遭取代Card gallery is deprecated.

    使用此功能的現有應用程式目前依然可以繼續執行,不過您無法新增卡片資源庫。Existing apps that use this feature will continue to run for the time being, but you can't add a card gallery. 請將卡片資源庫取代為新的編輯表單顯示表單控制項。Please replace card galleries with the new Edit form and Display form controls.
