Hello @svalais ,
it is not possible to use a result tag from one report to another report.
There is a workaround, where you take a result from Report A and show it in a reconciliation template Then, let the result from the reconciliation template appear in Report B.
You can find a case using the reference values across templates by using result tags also on the community: CASE reference values across templates by using result tags
I hope this workaround answers your question,
Kind regards
Sofie
