Let's say you want to add a field, a system view, edit or add a form, or make other adjustments to an entity and you'd like those changes to be part of the unmanaged solution so that they can be saved in future releases. You may be initially concerned to find that the entity you wish to change is missing from the list, but the steps below should guide you to getting the entity where you need it so you can make your changes successfully.
Click the Arrow Next to Entities to View Entities in the Solution
If your entity is there, then you can proceed with your changes.
If your entity is missing proceed through the following steps.
In the toolbar select Add Existing and select Entity
Click Ok
Click Add All Assets and Click Finish
This will allow you to bring over everything as it is in your default solution. While CRM gives you the opportunity to bring over different parts of the entity, unless you are doing some advanced custom development it is best to just bring everything over to avoid missing key details that could cause you problems later.
Select Yes or No in the Missing Required Components Page and Click Ok
CRM suggestes bringing over any related entities into your solution. The idea behind this is that if you ever moved this unmanaged solution to a new CRM independently, all the pieces would be there. However, in most cases this unmanaged solution will be part of a Cobalt solution release that has all the additional entities so it is up to you. Clicking Yes means that these additional entities get added to your Entity List. Clicking No means that they are not added. I generally say go ahead and add them as often users making a change to one entity find that they may want to make updates to related entities later.
