5 Tips for Creating New Fields in Dynamics 365/CRM

Now that you have a fresh CRM system, you are getting ready to add many new fields to customize for your business. Before getting started take a few minutes to plan your implementation using these tips:

1.       Define the use of the field – What kind of data will this be used for? Do you want to trigger any workflows or other automation from this field? How will data be entered? After a field is created you can change the field name and size (in the case of text fields), but you cannot change the field type.

2.       Think about current and future reporting needs – text fields are very difficult to report on. If this may be used in a report, think about using an Option Set instead. If necessary, you can have an Option Set with an additional “notes” fields to capture other data.

3.       Option Set vs Lookup field – When using an Option Set, determine how often the options may change? Who will be notified when they change? How often and how quickly may they need to change? Depending on the answers to these questions, you may want to consider using a Lookup instead. In this model, you would create another simple entity and users would select from the list of all records in that entity. This allows you to deactivate and add new options quickly. You can also store additional data for each option if necessary.

4.       Make Required if possible – Ensure users will enter data in the new field by making it required. If it cannot be required all the time, consider if you can use a business rule to make it required in certain circumstances.

5.       Use a Sandbox environment – any customizations should always be created in a sandbox or development environment and moved to production with a solution. This is important so it can be tested and reviewed before it starts being used. This allows time to ensure you choose the correct field type or delete and re-create if necessary. Once users are entering data in the field, if the field type needs to change you will need to create a new field and migrate the data from the old field. Additionally, you want to ensure your sandbox environment is as close as possible to production so that you do not potentially overwrite changes in a future solution (for example, this field was created directly in production then two weeks later a solution with the same entity causes that field to be removed from the form).

​Thanks Gaurav. The Tool Tips that show the description is a great feature. Also a great reminder to be careful if you decide to change Out of the Box features for a different use because of the display and schema name mismatch.

Very good post. Handles something very basic but critical topic. I make it a point to always use description box ardently to explain the use of field in brief so that user can use hover over function and at the same time an admin can validate the fields easily for data migration jobs in future. 
Another important thing, in my opinion, to keep in mind is to use well thought field names because even though you can change the display name easily, users still see system name for fields while doing advanced find and it may confuse some.
