How to restrict the variant from change
We had a problem where by mistake we have changed the variant of the program and it created a huge impact. Actually there is a standard program which releases the process order(Through background job). We have 5 plants. 1000,2000,3000,4000 and 5000. In one variant it was suppose to release only order for plant 1000. But due to manual error (By mistake deleted the plant in variant parameter and ran the background job) in production we have kept the field of plant as blank and it released all the orders for all plants.
Is there any way so that in normal production the variant can not be changed? Is it possible to restrict the change of variant through authorization?
