Start by reproducing the issue with the provided Python snippet against a workbook using both Impala extract and Oracle live connections. Compare PDF or CSV output when the extract and live-connection filters are supplied through PDFRequestOptions; done means all specified filters affect the generated file. Check the seven existing comments for additional reproduction details before choosing an implementation path.

Description

help wanted needs investigation Server-Side Enhancement

Describe the bug
Our workbooks contain data sources in extract mode for performance optimization. However, some data sources that are required for annotating the data need to remain in live connection mode to enhance the user experience. When we generate a pdf or csv from a view using the TSC package, all parameters in the extract are considered by the code, but the filters specific to selecting data in the live connection are ignored.

Versions
Details of your environment, including:

  • REST API version: 3.21
  • Python version: 3.9
  • TSC library version: 0.31

To Reproduce
Steps to reproduce the behavior. Please include a code snippet where possible.
We have a workbook with Impala connection (Extract) and oracle connection (Live connection).

Python code:

import tableauserverclient as TSC

SERVER_URL = 'your_server_url'
TOKEN_NAME = 'your_token_name'
TOKEN_VALUE = 'your_token_value'
SITE_NAME = 'your_site_name'
VIEW_NAME = 'your_view_name'
WORKBOOK_ID= 'your_workbook_id'

# initiate server connection 
server = TSC.Server(SERVER_URL, use_server_version=True)

# Use Personal Access Token for authentication
tableau_auth = TSC.PersonalAccessTokenAuth(token_name=TOKEN_NAME, personal_access_token=TOKEN_VALUE,
                                                site_id=SITE_NAME)
server.add_http_options({'verify': False})
server.version = '3.21'
server.auth.sign_in(tableau_auth)

# get workbook object 
workbook = server.workbooks.get_by_id(WORKBOOK_ID)

# populate view and specify filter parameters on the worksheet
server.workbooks.populate_views(workbook)
# Find the specific view by name
 view = next((v for v in workbook.views if v.name == VIEW_NAME), None)
req = TSC.PDFRequestOptions(maxage=-1, page_type='unspecified', orientation='landscape', viz_width=1200,
                                     viz_height=1000)
req.vf('country', 'Germany')  # parameter in extract
req.vf('company', 'abc')  # parameter in extract
req.vf('selected', 1)   # parameter in live connection

# populate pdf file
server.views.populate_pdf(view, req_options=req)

# write pdf file
output_file = "test.pdf"
 with open(output_file, 'wb') as file:
         file.write(view.pdf)

Results
What are the results or error messages received?
The PDF generated with the above code produces a report that ignores the "selected" parameter. The expected behavior is that the PDF should be generated considering all specified parameters, including those associated with the live connection.

NOTE: Be careful not to post user names, passwords, auth tokens or any other private or sensitive information.
