What I was trying to get from my previous request was whether you were hitting a very specific issue (attribute in Maximo not being set, wanting to skip certain updates, etc.). It sounds like you're really starting on building the integration. Unfortunately, building an integration is really outside the scope of this community. Integrations are time intensive exercises that require deep knowledge of each product to build and lots of design discussions. For example, in Maximo you can send to Maximo via SOAP webservices, REST web services, table integrations, or file (XML or CSV). You can also pull from the external system via multiple methods. Every choice has pros/cons and sometimes you're forced to use one over another based on restrictions (one product not supporting certain options, not having network connectivity between the systems, etc.). Realistically, you should try and team up with a business partner in this space to ensure you have a successful project.
