When you create an entity with CRM 4.0 you will make a decision to allow Notes or Activities for the given entity as shown below.

Out of the box with CRM 4.0 this section shown above is greyed out once the entity is created, which means it cannot be changed.

However, I have a solution which allows you to change this without having to delete the entity and all your hard work in order to change it.

Follow the steps below to change the Notes or Activities for your entity (Note: This is NOT supported, so only do this at your own risk):

• Export the entity to you want to change (Go to Settings > Customization > Export Customizations and select the entity and choose Export Selected Customizations)
• Unzip the customisations.zip file to obtain the XML file
• Open the XML file in Notepad.exe (or XML editor of your choice)
• Locate the XML node within the customisations.xml file:

<HasRelatedNotes>True</HasRelatedNotes>
<HasRelatedActivities>True</HasRelatedActivities>

The values inside these two attributes indicate if the entity should have Notes or Activities. Set each one to True if you require them, otherwise False to not allow them for the entity.

• Backup all your customizations i.e. Export All Customizations. Once you have made the XML change, delete the entity with your CRM 4.0 system you want to change. Yes this is ok. You have just exported it.
• Use Settings > Customization > Import Customizations and import the XML file which contains your entity.
• Publish your customizations.
• Now check your entity. You should notice the section with Note and Activities will be set depending on your values set in the XML file earlier.

Easy!

Now that must save you a lot of work.  Remember this is NOT supported, so only do this at your own risk. However I have done this in the past will successful results.
