Table or FM for Project Actual Cost similar to S_ALR_87013532 report
I am developing a custom report where i need to display project and actual cost. Please let me know is there any database table or function module to get the project cost. But we have a standard report(tcode S_ALR_87013532) to display the actual cost, I was not able to find the logic to calculate actual cost.
