Hi Zainab,
Docentric AX intercepts the data from the SSRS pipeline. If you do not see the data, it has not been read for some reason. Maybe there is a setting that prevents this, maybe there is a customization. You can investigate this with a functional consultant and a developer.
You can also run a report and generate a DDSP file. Then check the DDSP file with some text editor, like Notepad or even better Notepad++. You can also load this DDSP fire using Docentric AX Designer in MS Word. The screenshot below shows the SalesInvoice.Report template where the Review sample data button (see #2) has been pressed to show the data for the report. This will open the report data where we can search for values we are interested in.
Kind regards,
Albin
