Update Category class codes G/L


I need to change quite a few class codes in ten branches. I thought G41311 (5) would get it done, but I'm probably entering something wrong. Any guidance will be met with many thanks.
Be sure you have the processing option for the G/L Class set to a Y as you see below.
Update General Ledger Class Code Y

Also be sure to use the data selection for which branches you want the item G/L Classes updated with the Item Master value. The Item Location File
(F41021) G/L Classes will also be updated. You can also select only specific items if you choose.

This does work we use this several times throughout the year.
Thanks for the reply.
I'm missing something. The only field I select is the G/L class and the the query ends in the JobQ
