How we can Set Custom Sales Stages and their Probability in Opportunity Page

Hi Folks,

How we can Set Custom Sales Stages and their Probability in Opportunity Page?

Stage 1 : Product Evaluation 10%
Stage 2 : Product qualification 25%
Stage 3 : Negotiation 50%
Stage 4 : Order 90%
Stage 5 : Payment 100%
Stage 6 : Lost 0%

go to Dropdown editor and search for sales_probability_dom the Item Name is the Item Name of the sales_stage_dom and the Display Label is the value that will show, so if you add one in sales stage you should add one in the sales_probability_dom

best regards
