Dynamic Budgets uses a CompanyDB search parameter to allow you to select which company you wish to work with.
CompanyDB is the 5 letter technical acronym used to refer to the Company SQL Database, and full Company Names typically have many more characters and would require a much wider drop down field in the search parameters.
These non editable values can be seen in Manage Company Databases.
If users would prefer to see full company names in the Subtotaling rows of the Report Formats you can select Company Name or CompanyDB In Define Row Formats.
Company reporting tags 1-5 can be entered and updated in System Management / Companies / Bulk Company Management
