Introduction

If you have encountered an issue with an FME workspace and are unable to resolve it, this guide will help narrow down the problem to its simplest form. This process should help solve the issue or ensure that you receive a timely solution from technical support.

The following diagram displays the process:

Step 1: Reproduce the Issue

“我的工作空间无法写入任何数据！”

Identify the exact steps that causes the issue to occur. This may be as simple as running a workspace or something more complex such as adding a series of transformers. You will need to be able to perform this procedure again in the steps below.

Step 2: Narrow the Focus

“My workspace seems to fail as there are no features exiting the Clipper’s Inside port!”

想想这个问题，目前在工作区中不同的对象。你在阅读，写作和/或转换数据？尝试将问题缩小到具体的东西。

重要线索：

The feature count stops at a particular transformer

该日志包含有关对象的错误或警告

The output dataset is unexpected or incorrect

数据未能被读入工作空间

Data is not written

有用的提示

如果你是当你运行你的工作空间，请使用以下方法，帮助遇到的一个问题，缩小问题出在哪里是来自：

Run With Full Inspection: Runs the entire workflow and then allows you to inspect the data at any point in the workspace. This option is flexible but can take longer as you must process all the features first.

Run With Breakpoints：在一个特定的断点，允许亚搏在线你通过FME Workbench中的功能进行可视化功能停止工作流程。此选项是快捷的使用，因为它会在第一个功能，而不是运行整个工作区停止。

Once you have an idea of the general area where the problem exists, you can move on to the next step.

Step 3: Test Variables

“I’m going to try using only a single feature from the dataset”

Making small changes and testing is a great way to get to the source of an issue. For example, changing a workspace to read a smaller set of the same data, can test if a particular feature in that dataset is causing the issue. Below is a simple procedure to use:

测试Procedure:

Locate a variable that can be modified

Make a change to the variable

通过导致问题发生再现步骤来运行

Record the outcome

重复（如果结果是没有什么不同）

The following highlights example variables that can be utilized withStep 1of the Test Procedure:

Variable Type	Example Variable
Workspace	Format 特征类型为READ Specific Parameters (Readers, Writers, Transformers) Number of Features 特色的内容（属性架构和几何） FME Version
Environment	Installed Software and Operating System Environment Variables Network Access 用户帐户权限 Hardware

The following highlights example changes that can be used withStep 2of the Test Procedure:

Change Type	Example Change
Workspace	Limit the amount of features being read (See最大Featu资源来读） Add a Tester to filter for specific types of data Write using a different format Change parameters back to the default setting Remove and re-add the component 重新使用所述输入数据的一个小样本Cre atortransformer. 写到不同的位置/数据库/模式 Drop database tables and have FME recreate them
Environment	Run your FME with your workspace on a separate system inside the network 网络之外的系统（如果可能）上运行您的工作空间 测试在FME较新版本的工作区

Try anything that you think may lead to a different outcome!

Once you have made a change that creates a different output, proceed to the next step.

Note: If you were unable to make any changes that resulted in a different outcome and have exhausted every variable, proceed to Step 6: Go Direct to Source.

步骤4：分析结果

“简化的数据集修剪！这意味着，在我的数据的特定功能造成了此问题不理发器！”

这一步是设计用来解决问题或将决定下一步做什么。下面是处理的流程图：



When a specific change alters the workspace outcome, it should help you point to a possible root cause for the problem.

Root Cause Examples:

的特定特征

Geometry Type

Incorrect Format Parameter

Spatial Reference (mismatched coordinate systems)

Operating System

注意：当改变似乎与特定的计算机，你可以Generate a System Information Filefor each environment to help narrow down the differences.

如果问题是你的分析后，仍然没有得到解决，那么请继续下面。

(Optional) Step 5: Go Direct to the Source

在某些情况下有可能，这个问题是由FME软件以外的东西造成的。在这个测试中，你应该尝试不使用任何FME软件来复制相同的功能，看看根本原因可以被发现。与组件，如数据库，Web应用程序，复杂的格式和Python脚本时，这是一个重要的步骤。

Direct to the Source Examples:
问题: FME fails to read from an Esri Geodatabase.
测试: Use the ArcGIS for Desktop product to ensure the data can be read.

问题：连接到网站时出现错误时，使用HTTPCaller。
测试：尝试通过Web浏览器连接。

如果问题仍未得到解决，然后进入最后一步。

（可选）第6步：联系技术支持

请完成以下,以确保您receive timely and correct technical assistance.

6a: Simplify the Workflow

这里的目标是创造该问题的一个非常简单再生产。

读者：
为了简化的读者，请执行下列操作之一：

use Save As in Data Inspector to save a small sample back to the same format.

Recreate a small sample of the data using a创造者transformer.

使用Recorder变压器存储数据和Pla yertransformer to play it back. This method is especially useful for database formats. See here for a step-by-step guide:使用记录器和播放器。

If the issue requires that the specific reader format be present, then create a small subset of the data to submit with your case. To do this in FME, use theClipperorSampler变压器创建数据的新版本的功能有限。

Transformers:
当一个问题可以缩小到工作流程中的一个特定的变压器或变压器系列，放置亚搏在线Recordertransformer directly before this area and record the data. Then replace with a Player.

编剧：
换上作家记录仪or检查员transformer whenever possible.

Example of a simplified reproduction:


注：每个简化步骤后，确保问题仍然存在。如果在此过程中，您发现该结果已经改变了，回去到上面的步骤5和分析新的信息。

6b: Disable Unrelated Objects

停用未与此问题相关的任何组件。这些对象可以是工作空间内的读者，作家和变压器。

每次更改后运行的亚搏在线工作流程，以确保问题依然存在。

Examples:
问题：在运行时读取数据时FME的错误。
Process: Disable all transformers and writers from your workflow.

问题：FME一个StatisticsCalculator变压器内崩溃
Process: Disable writers and transformers located before or after the StatisticsCalculator that do not cause the issue to occur. Attach a Logger transformer to the StatisticsCalculator to ensure the data flows through.

6C：保存为模板文件

保存工作区为模板（.fmwt扩展）。这保证了它可以运行完全相同的方式该文件包含了工作区的副本和所有运行所需的数据文件。一步一步的指导可以在这里找到：Creating a Template File。

6d: Send the Reproduction to Support

This step will create a request on the Safe Software support ticketing system.

收集以下资源：

The workspace template

Log files

系统信息报告（看这里for information on how to generate this report)

任何辅助材料（屏幕截图，视频，文档）

完成此form（附加文件），以提交您的问题，以技术支持。
