Hi Kobra Alizadeh ,
I got the response from the team.
"Currently running unpublished notebook as notebook activity in pipeline is not support on Synapse, but reference running unpublished notebook in another notebook is supported . It’s by design."
Appreciate if you could share the feedback on our Azure Synapse feedback channel, which would be open for the user community to upvote & comment on. This allows our product team to effectively prioritize your request against our existing feature backlog and gives insight into the potential impact of implementing the suggested feature.
