How to pull data from VCHAINS app via Python API ?

Aasim

One of our users needs value chain customer data for approximately 538 listed companies. In the Workspace interface, she can easily view this data for individual companies via the VCHAINS app and export it to Excel. However, manually exporting data for all 538 companies one by one is not practical.
She tried to retrieve the data programmatically via the Python API (lseg.data and eikon), but this has not worked so far – the value chain fields do not appear to be accessible via the API.
1. Is there a way to retrieve value chain data via the Python API? If so, what are the correct field names and parameters?

You need to ask for the Excel formula, such as =RDP.Data, that can be used to retrieve the required data. Then, we can help you converting that formula to Python code. You can also refer to the How to Convert the =@RDP.Data Excel Function into Code Using the LSEG Data Library for Python article.

Alternatively, you can contact the VCHAINS product team to verify the data source.
