HI,
With more than 5 years of experience in SugarCRM setup and customization.I have served lots of companies from different sectors to fit their business logic in open source [login to view URL] of those sectors include Finance, Universities, Publishers, Cosmetic Retail Chain, Renewable Energy and many more
I have worked on almost all versions of Sugarcrm (CE, Professional, Enterprise). Including tasks related to creation of new modules, adding new fields, creating logic hooks, reports, web-to-lead forms, workflows, schedulers, upgrade version and data migration from other CRM.
As per your provided details we will need to create a function to generate this special ID which will be called using logic hook while saving the record and will be visible in detail / list view. As we will store it in a database field so we can also add it to search panels so you can search records as suggested.
Note: As per discussion on Skype we will need to consider repeated auto number for lifts related to different buildings.
Thanks,
Ashish
