AME_Repository Contract

Hi:

Why Repository Contracts that do not meet condition in approval rule are stuck in Pending approval status?

For example:

I've created a rule based on condition: contract type = ZZ

I've created a repository contract with type: ZZ and approval process works fine

I've created a repository contract with type: YY and contract status is stuck on "Pending Approval"

Why is this? How can these contracts "reach" Approved status?

Thanks in advance,

Beatriz
