Hi @Anonymous User,

I assume you have access to administrating an ArcGIS Enterprise.

A simple workflow for your custom widget may be:

* Select Features,
* Send Queries to GET data,
* Summarise/Aggregate JSON data,
* Send JSON data to GPService,

Your GPService will then output the pdf from the JSON data. Note, step 2-4 above can be omitted and completed in the GPService if your data is large (i.e. the client application is slow to execute the queries/aggregations).

For PDF reporting, you will need to install a 3rd party Python modules to your Server framework's python. See Deploying custom Python packages for ArcGIS Server . Modules which you might consider for building your PDF from the JSON data are:

* LaTeX,
* ReportLab,
* PyPDF,
* Pdfkit...

There are many more. You should probably try see which modules you like best before installing a module on your server.

As for Maps, you can use the ExportMap REST operation which native in all MapServers or customise and deploy a layout to a printing service by following these instructions.

Thanks for the reply. I have been working on this customize widgets from past 3 years.

I have been confused how to generate the pdf with map and table data as there alot of third party apis where i can export html data to pdf. but in my case i need to use only javascript api and gp services. could you please let me know the way or idea how to generate the reports.

Did you try the screening widget? You can specify which fields to include
in the report from one or more layers.
