how to create &variant for background job SWWCLEAR

Hi Experts,

job SWWCLEAR is failing with error message variant &0000000000000 does not exist.

I have checked in SM37 job log that variant &0000000000000 is the correct variant for job SWWCLEAR since

there are multiple job instances of SWWCLEAR which finished successfully with variant &0000000000000 at earlier dates.

But after server got refreshed, job SWWCLEAR is failing with error message variant &0000000000000 does not exist.

Can anyone please guide what corrective action I should take now to resolve the error.

Thanks,

Sonali.
