You can add your own user-defined fields to server-mounted data sources. For example, you can create your own edit boxes, numerical fields and check boxes. This might be useful if you are integrating Asta Powerproject with other systems. For example, you might have a stock control system and want part numbers from the stock control system to be stored in your project with resource properties. Or you might want to provide additional information in your project so that it can be referenced by the stock control system.
You can also add user-defined tables to server-mounted data sources. These are collections of fields, which you can define, that appear in a grid. You can create user-defined enumerators and include these in user-defined tables; these enable you to select from a list of pre-specified values in a dropdown list.
