Each division within my customer's company is allocated 300 hours for application enhancements and development per quarter. We need to know how many hours have been utilised to date per quarter and this needs to reflect whenever we create a new Release for a Division. So i have a Division BO that has hours used number field and has a relationship with Release BO (one Division can relate to many Release Records). I also create an editing business rule for Release that shows the hours used for the division when selecting the Division. I just don't know how to take the release Total Time Spent (will convert to hours) and add it to the Division Hours Used, taking the current Quarter into account. Any help would be greatly appreciated.
