Local Purchase % for residential construction

Good morning - I am modeling the impacts for residential construction. I have data for two variables: Labor ($4.5 million) and Materials ($3.9 million). My question: How do I adjust the Local Purchase Percentage for materials ONLY. My current steps: 1. I set up an Industry Change Activity with Level 1.0. 2. New Event is 37. 3. Total Industry Sales is $8.4 million (Labor + Materials) 4. Employee Compensation is $4.5 million (override the Implan's default values) 5. Adjust the Employment by dividing Employee Compensation by Output per Worker (From the Customize -> Study Area Data window. The Local Purchase Percentage for labor is about 98% (based on Implan data). The Local Purchase Percentage for materials is about 70% (based on client input). Is the best approach to create two separate Events? Event 1 - Compensation 1. New Event is 37. 2. Total Industry Sales is $4.5 million (Labor only) 3. Employee Compensation is $4.5 million (override the Implan's default values) 4. Adjust the Employment by dividing Employee Compensation by Output per Worker (From the Customize -> Study Area Data window. 5. LPP is the default. Event 2 - Materials 1. New Event is 37. 2. Total Industry Sales is $3.9 million (Materials only) 3. Employee Compensation is $0 (override the Implan's default values) 4. Employment is 0. 5. LPP is 70% Also, please note the links in Implan to previous posts about Capital Expenditures or Parts-by-Analysis are broken. Thanks.
