18 Jul 2.45 Ιn filling the documentation for participating at tender I’ve found the wording “solution ID”. At which ID it refers? At the Grant Agreement ID?

[upd. 28.07.202] The ID number is automatically given by the the Innovation Procurement Platform:  https://innovationprocurement.com/.

The Solution ID Number can be found in the section “My Tender”, as soon as you start your submission.
