Creation of resource plans without users

[Alberto12]

When creating a Resource Plan for a Demand in its first stages, it is common not to know exactly which specific resources will be involved.

Does anybody know if there is a way to create Resource Plans that doesn't allocate users but creates like a placeholder without users?

Will you have the group that might work on the demand at the time of RP creation? But usually the RPs are created after determining the potential resources. If you are creating RP to get the estimated budgets, you could use the opex costs instead? Just a suggestion but i would like to know why do you need an RP as a place holder
