AM02.1 - Methods
**Form purpose
Use Methods (AM02.1) to define the methods that asset books use for
calculating depreciation, replacement cost, and insurance values. Lawson
provides six standard depreciation methods and lets you define your own as
well. Methods can calculate depreciation in one of three ways: compute
statements, annual percent tables, or units of production (UOP) tables (annual
or by period).
**Prerequisites
To load the system-defined depreciation methods and the dictionary values you
can use in compute statements, you must run Dictionary Load and Listing
(AM550).
**Required fields
The Method and Type fields are always required. The following fields are
conditionally required.
. If your method uses a compute statement, the Statement field is required.
- If your method uses a percent table, you must define at least one Percent
field.
- If your method uses an annual UOP table, you must define at least one
Annual Estimate field.
**Decision/Impact
- If your method uses a compute statement, you can also select an
optimization method. The Asset Management system will switch to the
optimization method whenever it is advantageous to the company, if the book
that uses the principal method is defined with the Method Switch field set to
Yes.
- If your method uses a UOP annual table, you must enter actual UOPs at the
end of each year. The system uses the actual UOPs for its calculations. If
the asset life is more than 13 years, you must continue defining the method on
the UOP Table Yr 14-26 form tab. The system keeps track of the total estimate
units.
- For each year that you define on the UOP Table form tabs, you can choose
the Periods button to define depreciation calculations by period.
**More help
- A compute statement consists of dictionary items, numbers, and
mathematical operators. It must always be expressed as a formula. If you want
to indicate an actual amount, express it as amount * 1 or amount + 1.

calculations involved in the compute, percent and UOP depreciation methods,

Updated Files
AMCOMPUTE - Used to store the Lawson-defined compute statement methods
(straight line; 125, 150, 175, and 200 percent declining
balance; and sum of the years digits) and optional user-defined
methods.
AMMETHOD - Primary file. Used to store the Lawson-defined and optional
user-defined methods that asset books use to calculate
depreciation, replacement cost, and insurance values.
AMTABLEPCT - Used to store user-defined percent table methods that asset
books use to calculate depreciation, replacement cost, and
insurance values.
AMUOPPDS - Used to store user-defined annual and period units of
production table methods that asset books use to calculate
depreciation, replacement cost, and insurance values.

AM02.2 - U O P Table Periods
**Form purpose
Use U O P Table Periods (AM02.2) to maintain estimated and actual units of
production by period. You can define up to 55 periods, divided into three
sections. You can define depreciation calculations by period for each year
that you define on the UOP Table form tabs on Methods (AM02.1).
**Prerequisites
You must access this form through Methods (AM02.1).
**Required fields
The Method field is required and defaults from the method field on AM06.1. The
Year field is also required.
**Decision/Impact
UOP depreciation calculations by period let you choose one of three period
conventions:
- If you select Actuals or Estimate (AE), the system uses actual UOPs if
they exist. If actual values do not exist, the system uses estimated UOPs.
This is the default.
- If you select Estimates Only (EO), the system uses only estimates for the
calculations. If estimates do not exist, the system substitutes zeros.
- If you select Actuals Only (AO), the system uses only actual values for
the calculations. If actual values do not exist, the system substitutes zeros.
