Standard Operation Description

We changed one of the standard operation description, all new routing/operatrions has obtained the new description, Old ones still have the old descriptoin, is there any process to touch the old ones and update them to have the new descriptions? If not is it safe to update the descritpion for this STD. operation in the tables WIP_OPERATIONS, BOM_OPERATION_SEQUENCES instead of manually do it thru the forms.

We are on R11.

Thanks
