Using Calculated Fields
You can use the global edit feature to place the contents of a calculated field into a user defined field where it is accessible to third-party applications.
An expression defining a calculated field can include the following elements:
| Expression | Description | ||||||||||||||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Constants | You can include text, date, numeric, and logical constants in a calculated field or global edit according to the following guidelines:
|
||||||||||||||||||||||||
| Other calculated fields | Expressions defining calculated fields can include references to previously defined calculated fields.
Note: A calculated field cannot include a reference to itself.
|
||||||||||||||||||||||||
| Mathematical operators | You can include the following mathematical operators in a calculated field or global edit expression:
Expressions containing mathematical operators are evaluated according to the normal rules of precedence:
|
||||||||||||||||||||||||
| Logical operators | You can include the following logical operators in a calculated field or global edit expression:
|
||||||||||||||||||||||||
| Duration operators | You can include the following duration operators in a calculated field or global edit expression:
|
||||||||||||||||||||||||
| Field names | When including a field in an expression for a calculated field or global edit, you must enter the name of the field and not the descriptive name that is displayed in spreadsheet column headings. For example, if you want to define a calculated field expression that references the field containing early start dates, you must identify the field as ESDATE, not Early Start. | ||||||||||||||||||||||||
| Functions | Calculated field and global edit expressions can contain a number of functions. For more information, refer to the topic "Using the Functions Dialog Box." | ||||||||||||||||||||||||
| Relational operators | Expressions for calculated fields or global edits can include the following relational operators:
|
||||||||||||||||||||||||
| Character operators | You can include the following character operators in a calculated field or global edit expression:
|
||||||||||||||||||||||||
| Project Level Variables | You can instruct Open Plan to use project-level data from the current project or external subproject by specifying
_proj. or
_subp. as a prefix to the field. For example:
|
In addition, an expression defining a calculated field can also include the special operators used in filters.
To display a list of available calculated fields, click the Calculated Fields command on the Tools tab to display the Calculate Fields dialog box.
If you hover your mouse cursor over a calculated field, Open Plan displays the definition of that calculated field as a tool tip.
