Create Maintain Work Orders Accomplishments - Work Order Time Entry - P31122 Erro

I am trying to enter labour against a work order using Create Maintain Work Orders Accomplishments - Work Order Time Entry - P31122, and I am getting the following error message:

Status Invalid for Change:

Cause...The Work Order Status is past the allowable
change status that was entered in the P311221 processing options

Resolution...Select a Work Order with a status of less than the processing
option value

When I check the processing options, the default for the Work Order Status is blank.  I am assuming this is what the error is referring to, but I do not know what it wants in that field.  I tried using 'MD' - 'W/O Standing W/O's ' which is the status of our Work Orders, but I still get the same error message.  Can anyone tell me what I need as the processing option in order to make this work?
