Run MassAllocations Schedule

Hi I'm trying to run a mass allocations program every saturday which use an SQL query to fetch the currently open GL period. I've set the mass allocations job up to run from a request set and below are the parameters I am using:

command_mode: Type Constant: C

set_of_books_id: Type Constant: 2

incremental_flag: Type Constant: N

average_je_flag: Type Constant: N

allocation_batch_id: Type Constant: 1622

PERIOD_NAME: Type SQL Statement: SELECT PERIOD_NAME FROM GL_PERIOD_STATUSES WHERE application_id = 101 and set_of_books_id = 2 and sysdate between start_date and end_date and closing_status = 'O'
