For example, in a recent project, I used XD to create custom dimensions for cost centers and projects, enabling flexible reporting and data analysis. I configured member formulas and confirmation rules to ensure data integrity.How do you approach debugging a complex OneStream business rule that is not producing expected results?I first review the business rule logic and check for syntax errors. Then I use OneStream's diagnostic tools to trace the rule execution and examine intermediate values. I also check data sources and mapping to ensure input data is correct. If needed, I add temporary logging to isolate the issue.Describe a time you had to integrate OneStream with an external data source. What challenges did you face?I integrated OneStream with an ERP system using custom data connectors. The main challenge was handling data transformations and ensuring consistency. I designed transformation rules to map fields and used SQL to validate data. I also set up error handling to log and resolve mismatches.How do you ensure the user interface you build is intuitive for end-users?I focus on user-centered design by understanding their workflow and pain points. I use dashboards with clear navigation, advanced formatting for visual cues, and parameters for customization. I also gather feedback during UAT to refine the interface.What is your experience with the federal PPBE process and how does it impact OneStream implementations?I have worked on projects involving the PPBE process, which requires detailed budgeting and planning. OneStream can be configured to support multi-year planning, scenario analysis, and compliance reporting. I ensure the solution aligns with federal regulations and provides audit trails. ## General information Requisition # R68221 Locations USA-Remote Work Posting Date 05/30/2026 Remote Type Fully Remote Time Type Full time ## Description & Requirements Elevate your career with MANTECH International Corporation!
