Defining Unit of Measure Conversions

Unit of measure conversions are numerical factors that enable you to perform transactions in units other than the primary unit of the item being transacted. You can define:

Unit of measure conversions are not organization-specific.

You must define a conversion between a non-base unit of measure and the base unit of measure before you can assign the non-base unit of measure to an item.

Specifying Which Conversion to Use

When you define an item you decide which type of unit of measure conversion to use:

Unit of Measure Conversions During Transactions

Whenever you enter an item's quantity, the default is the primary unit of measure for the item. The list of values for the unit of measure field displays all units of measure for which you have defined standard and/or item-specific conversions from the primary unit of measure.

Transactions are performed in the unit of measure you specify. The conversion happens automatically and item quantities are updated in the primary unit of measure of the item.

Attention: Inventory transactions and on hand balance supports decimal precision to 5 digits after the decimal point. Oracle Work in Process supports decimal precision to 6 digits. Other Oracle Applications support different decimal precision. As a result of the decimal precision mismatch, transactions another Oracle Application passes may be rounded when processed by Inventory. If the transaction quantity is rounded to zero, Inventory does not process the transaction. It is therefore suggested that the base unit of measure for an item is set up such that transaction quantities in the base unit of measure not require greater than 5 digits of decimal precision.

arrow icon   To define a Standard conversion for any item:

  1. Navigate to the Unit of Measure Conversions window.

  2. Select the Standard tabbed region.

  3. Enter a unit of measure.

  4. Enter the conversion factor by which the unit of measure is equivalent to the base unit of measure established for this class.

    For example, if one DZ (this unit of measure) is equivalent to 12 EA (base unit), the conversion factor is 12. Or, if EA is equal to one-twelfth of a DZ, the conversion factor is 0.08333.

  5. Save your work.

arrow icon   To define a conversion for a specific item within a unit of measure class (Intra-class):

  1. Navigate to the Unit of Measure Conversions window.

  2. Select the Intra-class tabbed region.

  3. Enter an item.

  4. Enter a unit of measure.

  5. Enter the conversion factor by which the unit of measure is equivalent to the base unit of measure established for this class.

    For example, if one LB (this unit of measure) is equivalent to 16 OZ (base unit), the conversion factor is 16.

  6. Save your work.

arrow icon   To define a conversion for a specific item between unit of measure classes (Inter-class):

  1. Navigate to the Unit of Measure Conversions window.

  2. Select the Inter-class tabbed region.

  3. Select an item.

  4. Select the destination base unit of measure of the class to which you are converting a unit of measure.

  5. Enter the conversion factor by which the source base unit is equivalent to the destination base unit.

    For example, if one ML (source base unit) is equivalent to one GR (destination base unit), the conversion factor is one.

  6. Save your work.

arrow icon   To make a unit of measure conversion inactive:

  1. Enter the date on which the conversion becomes inactive.

    As of this date, you can no longer use the unit of measure conversion.
