Ref: https://docs.oracle.com/en/cloud/saas/project-portfolio-management/19a/fapfm/implementing-project-execution-management-applications.html#FAPFM1724547 Topic - Submitting the Process to Maintain Project Resource Search Index: Procedure Submit the Maintain Project Resource Search Index job set to update the resources that appear on the Search and Evaluate Resources page when a resource manager searches for resources to fulfill project resource requests. The job set consists of a set of processes that facilitate efficient and rapid searches for qualified resources.
Resource managers can,t search for resources or view resource details if the search index isn,t available for a project resource request with qualifications or keywords. For project resource requests without qualifications and keywords, resource managers can search for and evaluate resources based on resource availability even if the search index isn,t current or available.
Caution: The search index isn,t available if the Maintain Project Resource Search Index job set process fails, or while the process is running.

To allocate the rental cost to the projects and tasks based on the raw costs of the tasks from the previous month, you need to do the following:
Allocate rental costs once each accounting period by using the "full" allocation method. This method allocates the entire source amount to the target tasks in one run.
Allocate to all eligible tasks and prorate the allocation by the total actual raw cost accrued for each task during the previous accounting period. This ensures that the source amount is proportionally allocated to the tasks based on their relative raw costs.
Define allocation basis by using Actual Amounts with a period-to-date amount class. This allows you to use the actual raw costs of the tasks as the basis for allocation and to use the amounts from the previous accounting period. https://docs.oracle.com/en/cloud/saas/project-portfolio-management/20c/oapfm/manage-project-costs.html#OAPFM2355951
