Each line item and version combination can have only one formula.

To select the version for a line item formula:

- Open the module in
**Blueprint**, and in the**Formula Scope**field for the line item, select from these options:

Formula Scope | Description |

All Versions | Line item formula applies to all versions. |

Actual Versions | Line item formula applies only to the Actual version. |

All versions except Actual | Line item formula applies to all versions, including the Current version but excluding the Actual version. |

Current Version | Line item formula applies to the Current version only. |

**Difference between Formula Scope and Add Version Formula**

Use the **Formula Scope** field when you want a formula to apply to a version and an individual line item.

Use the **Add Version Formula** option on the **Edit** menu when you want a formula to apply to a version and a line item subset in a module.

You can also add a version formula to the whole model.

When setting up version formulas, you might need to change the scope of one or more line item formulas so they do not clash.
