Understanding Computation Methods

The method of computation determines the fields to which you have access to affect the projected final values, and ultimately, the percent complete. Some methods can be assigned to accounts at the header level only. Other methods cannot be used with revenue accounts. Some methods let you enter (force) revisions that affect projected final values, while other methods use the system to calculate projected final values.

If the computation method lets you force projected final values, enter an incremental change (the number that you want to add or subtract) or the total projected final value. The job progress applications have separate fields for forcing units and amounts. Regardless of which method you use to affect the projected final values, the system updates the net change in the FA/FU ledger.

Update the percent complete and the system updates the F% ledger. If you cannot update the percent complete, the system calculates it automatically based on the method of computation. The system does not store the system-calculated percent complete in the F% ledger. Depending on the computation method, the system displays either the value from the F% ledger or the system-calculated value on the Job Status Inquiry form.

Because each computation method affects different ledgers, and because revised budget ledgers can include user-defined ledgers in addition to JA/JU, the tables describe the ledgers used in the calculations and the abbreviations used in the discussion of computation methods:

Ledger Type	Description
AA/AU	Actual amounts and units.
PA/PU	Open commitment (purchase order) amounts and units.
HA/HU	Projected final amounts and units
FA/FU	Projected final amounts and units that you force. The system adds the value in FA/FU to the value for the revised budget ledger to calculate projected final values (HA and HU).
IA/IU	System-generated revisions to the budget values.
F%	Percent complete value that you enter. The system does not update the F% ledger with system calculated percent complete values.
RA	Remaining units ledger. Because the system updates RA with unit rate values, the RU ledger does not exist. The system calculates remaining amounts using the formula: HA – AA.

Abbreviation	Description
RBLA	The sum of JA and other user-defined revised budget ledger amounts.
RBLU	The sum of JU and other user-defined revised budget ledger units.
PC	The percent complete that appears on the Job Status Inquiry form and reports. The system calculates this value for informational purposes. The system uses the percent complete for the job to calculate profit recognition.
RBLUR	The revised budget ledger unit rate, which the system calculates using the formula RBLA / RBLU.
AUR	The actual unit rate, which the system calculates using the formula AA / AU.
ETCU	The estimate-to-complete units. This is the estimated number of units that are required to complete the task.
ETCA	The estimate-to-complete amount. This is the estimated amount that is required to complete the task.
EACU	The estimate-at-completion units. This is the same as HU, except that it updates the BORG field instead of the net posting period field.
EACA	The estimate-at-completion amount. This is the same as HA, except that it updates the BORG field instead of the net posting period field.
RMA	The remaining amount, which the system calculates using the formula HA – AA.
RMU	The remaining units, which the system calculates using the formula HU – AU.

You can assign the following Information to each computation method:

• The type of account to which you can assign the computation method.

• The formula that the system uses to calculate the percent complete for the account, unless the computation method lets you enter it.

• The formula that the system uses to calculate the final projected units for the account.

• The formula that the system uses to calculate the final projected amount.

• The effect of changes on one account to related accounts (such as the header or detail account).
