Period Distribution: An Overview


If you are comfortable with the Budget and Forecast Doc types, and how budgeting is tracked in the Spitfire Management System, you may want to use the Period Distribution Doc type and the Period Distribution (PD) workbook. This post offers an introduction and links to additional information at the bottom.

The PD workbook draws information from your current budget (either in budget or forecast mode) so that you can spread project budget costs over financial periods representing the life of your project.  In addition, if the Period Distribution requires a Budget Revision to adjust the budget to match the Period Distribution, that Budget Revision is automatically created by default.

Prerequisites and Setup:

  1. System Admin tools:
    1. Make the Period Distribution site active through the Doc Types tool.
    2. Ensure that users who will create, access and use the Period Distribution document and workbook have the correct role capabilities (established through the Roles Maintenance tool).  See Period Distribution Workbook-Specific Capabilities 
    3. (optional) If users will switch between EAC (current budget) and FAC (forecast) as targets for the PD workbook, make the Post To field visible on the Period Distribution document through the UI Configuration tool [Part = Doc Detail – Standard; Item = Post To Targets].
    4. By default, Spitfire will generate a budget revision from the Period Distribution. If you do not want automatic budget revisions, turn the BudgetConfig  | AutomaticBudget Revisions rule off for Period Distribution through the Rules Maintenance tool.
  2. On your project:
    1. Give your Project Setup document both a Project Current Start and a Project Current Finish date.
    2. Approve your project’s Initial Budget document before attempting to create the first Period Distribution document

The Period Distribution Document:

You access the PD workbook from the Period Distribution document.

  • As long as the status of the Period Distribution document is In Process, you can open and make changes to the PD workbook as many times as needed.
  • When the Period Distribution document is Pending, the PD workbook can be opened but not edited.
  • When the Period Distribution document is Approved, by default, a Budget Revision is created and approved (see KBA-01300) and both the Period Distribution document and workbook become “closed” / read-only.
    • At this point, revisions to the Period Distribution are made through a new Period Distribution document and its PD workbook. Each new Period Distribution carries over all previously approved revisions.

The Period Distribution (PD) Workbook:

  • The Period Data worksheet is frozen to always display rows 1 – 8 and columns C – G. Cells in these rows and columns are also protected and don’t allow input.
  • Each line represents a unique combination of Cost Code and Account Category from your budget (work-breakdown-structure).
  • As many columns as needed are dynamically added to cover the range from start date to end date.
  • There are summary rows at the top in rows 4 – 7.
  • Cells with a yellow background indicate amounts remaining to be distributed.
  • Cells with a red background indicate amounts that are over-distributed.
  • Cells on row 8 with a green background (not shown) highlight the column representing the current period based on the current date.
  • Cells on row 8 with a tan background (not shown) highlight the target starting period for distributions whenever a change occurs to the starting period on a form. This is a momentary change to visually help you locate the correct starting period.
  • White cells show projected amounts, right-justified.
  • Green and grey cells are actual amounts, left-justified.
  • You can type directly in any of the white cells not in the restricted area.
