When you define an accounting class, you must assign valuation and variance accounts to it. When you issue materials to a job that uses this accounting class, the appropriate valuation accounts are charged. When the job is closed, final costs and variances are calculated and posted to the variance and valuation accounts. When the accounting period is closed, these journal entries are automatically posted to the general ledger.
For example to track recurring expenses -- machine maintenance or engineering projects -- with non-standard jobs, you can define and assign an accounting class with a type of expense non-standard to these jobs. The valuation accounts carry the costs incurred on these expense jobs as an asset during the period and automatically writes them off to the variance accounts at period close.
On the other hand, if you use non-standard discrete jobs to track production costs as assets, you can define and assign an accounting class with a type of asset non-standard. Asset non-standard discrete jobs are costed the same as standard discrete jobs. Valuation accounts are charged when material is issued to a job and final costs and variances are calculated and posted to the appropriate variance and valuation accounts when the job is closed.
You can analyze repetitive manufacturing costs by assembly regardless of the line on which it was manufactured by using the same accounting class for all lines that build that assembly. You can use the same class for all assemblies on a line to do line based cost reporting or you can use a different accounting class for every line/assembly association.
Variance accounts associated with Standard Discrete and Non-standard Asset accounting classes are charged when jobs are closed. Variance accounts associated with Expense Non-standard Discrete, and optionally Repetitive accounting classes, are charged when accounting periods are closed.
As noted in the following table, different valuation and variance accounts are required under standard versus average costing:
Account | Valuation | Variance |
---|---|---|
Material | Standard and Average | Standard and Average |
Material Overhead | Standard and Average | Standard and Average |
Resource | Standard and Average | Standard and *Average |
Outside processing | Standard and Average | Standard and *Average |
Overhead | Standard and Average | Standard and *Average |
Standard Cost | Standard Only | |
Bridging | Average Only | |
Expense | Average Only | |
*Applicable only if you are using the new cost processor. See: Setting Up Inventory Average Costing and Setting Up Manufacturing Average Costing | ||
Table 1 - 3. Standard Versus Average Costing Valuation and Variance Accounts (Page 2 of 2) |
Material | Normally an asset account this account tracks material costs. Under standard costing, it is debited at standard when you issue material to a job or schedule and credited at standard when you complete assemblies from a job or schedule, close a job, or close an accounting period. Under average costing, this account is debited at the average cost in effect at the time of the issue transaction and is credited when you complete assemblies from a job. |
Material Overhead | Normally an asset account this account tracks material overhead (burden) costs. Under standard costing, it is charged/debited at standard when you issue material with material overhead to a job or schedule and relieved at standard when you complete assemblies from a job or schedule, close a job, or close an accounting period. Under average costing, this account is debited at the average cost in effect at the time of the issue transaction. |
Note: When a job is completed and material overhead is earned, this account is not charged /credited. Instead, the material overhead account for the completion subinventory is debited. | |
Resource | Normally an asset account this account tracks resource costs. Under standard costing, it is charged/debited at standard when resources are charged to a job or schedule and relieved/credited at standard when you complete assemblies from a job or schedule, close a job, or close an accounting period. Under average costing, this account is debited and credited at the resource rate in effect at the time the resource is charged. |
Outside ProcessingNormally an asset account this account tracks outside processing costs. Under standard costing it is debited at the standard or purchase order cost when you receive items for a job or schedule in Oracle Purchasing. It is credited at standard when you complete assemblies from a job or schedule, close a job, or close an accounting period. Under average costing when you move job or repetitive schedule assemblies through an outside processing operation, it is debited at the resource's predefined rate or at the purchase order cost. See: Performing Move Transactions. | |
Overhead | Normally an asset account this account tracks resource or department overhead cost. Under standard costing it is debited at standard when resources are charged to a job or schedule. It is relieved at standard when you complete assemblies from a job or schedule, close a job, or close an accounting period. |
