Explanation
This is how CK can revoke Opportunity team access on an ad-hoc basis. Opportunity teams are groups of users who work together on an opportunity and share access to it. Users can add or remove team members as needed, and specify different levels of access for each team member. By removing a user's Opportunity team member, CK can revoke their access to the opportunity without affecting other team members or changing the sharing model.

Mapping the ERP unique ID to a custom external ID unique number field is the best way to meet the requirement of organizing data using the unique ID that is a number type in the ERP. An external ID is a custom field that has the "External ID" attribute, meaning that it contains unique record identifiers from a system outside of Salesforce. A unique number field is a custom field that has the "Unique" attribute, meaning that it does not allow duplicate values in the field. By mapping the ERP unique ID to a custom external ID unique number field, Cloud Kicks can use this field to match records during data import or update operations, avoid duplicate records or incorrect data, and maintain data integrity between Salesforce and the ERP system.
