Why can't a user select a plan when submitting an initiative?

If the user cannot select an plan, there are 4 potential reasons:

• The plan has not been defined.
• The plan is closed (validity date expired if defined).
• The plan is archived.
• The scope (Site or Organizational units) of the author is not or is no longer part of the scope of the plan. 

It is therefore necessary to find out if the plan exists and check its scope to ensure that the author is indeed part of it. If this is not the case, the scope of the plan must be modified on an ad hoc basis.
