Payroll question "Missing entry in status table for pay group MONTHLY"

I have added a MONTHLY to PayRoll → Pay groups.

Pay group : MONTHLY

Short code : MONTHLY

Pay group description : Monthy

Pay period cycle : MONTHY

Check form type : U.S

Prior entry periods : 0

Future entry periods : 0

Active date : 01/01/2000

Expiry date : 31/12/2154

But when I use MONTHY pay group in Pay Period Generated Earnings (or other ex : Journals-> Earnings), it has error : “Missing entry in status table for pay group MONTHLY”

Please help me

Thanks in advance. Sorry for my English
