Requirements analysis is very important phase of the software development life cycle (SDLC). It is used to build domain or conceptual models from requirements analysis. These models are helpful for defining stakeholders and functional requirements. Also, these functional requirements are easy to define for local systems, but they are very difficult to define for distributed stakeholders or systems. In this paper, we proposed a new approach to generate integrated requirements for a distributed system. This approach is composed of four steps: The first one is to generate an event table with a proposed template that suitable for requirements collection. This event table will be filled for each department and branch. The second one is to generate a normalized event table for all departments and branches. The third one is building and analyzing an integrated table to define the redundancy of functional requirements for all departments and branches. The final one is to generate and propose a new UML notation for distributed functional requirements. This approach is applied to a real ERP system as a case study and shows a significant result.
