RE: commissions in dynamics 365
Hi Sumaira
Since this is a custom built. You would require few starting points as to:
1. When it is treated that a commission would be granted or not (the criterias I mean)
2. Who all will be eligible for a commission?
3. What percentage will be treated as commission?
4. Is there a default commission based on success?
5. Do you need an approval workflow for commission process too before it is actually provisioned to a salesperson? If yes, who will approve it? Level of approvals required?
6. Is commision time bound? like monthly/yearly/bi-yearly?
Based on all that you can create a custom entity as a configuration entity.
You can then make use of calculated fields to calculate it against Opportunity entity. On its status change to Won you can have the calculations ready.
Hope this helps!
