Error during RFx for the SC if no plant in Org. Structure?

Hello SRM experts,

The SC 100XXXXXXX was created with plant P1 in SRM for the PR 100YYYYYY  in Plan Driven procument scenario. Now the Plant P1 has been removed from the SRM Org Structure. I am under the imppression that the system will not let me create an RFx for this SC, but I did create RFx successfully. Am I missing any confiugration here? if not, how can we handle this scenario, any ideas apppreciated?

Thanks
