What limitation of Salesforce-to-Salesforce must be considered for bi-directional integration?

Salesforce-to-Salesforce primarily facilitates the sharing of records and information between different Salesforce orgs, but it is not inherently designed for bi-directional integration. This means that while you can share records from one org to another, the initial setup does not support automatic or seamless two-way data exchange. This limitation makes it challenging when dealing with systems that require constant synchronization of data, as data shared in one direction may not automatically reflect updates or changes in the other direction. Thus, organizations must implement additional processes or tools to achieve true bi-directional integration.

The other options touch on potential limitations like record sharing limits and time delays but do not accurately capture the fundamental nature of Salesforce-to-Salesforce with regard to its lack of built-in support for bi-directional integrations. Additionally, while certain limitations exist, they do not encompass the significant challenge of achieving seamless two-way synchronization as discussed in the correct choice.
