Receivables lets you give discounts to your customers when they pay for their debit items before a certain date. Discounts are determined by the payment terms you assign to your customers. You can also choose whether to allow discounts for partial payments and specify how you want Receivables to calculate the discount on your invoices.

The WIP valuation accounts are charged when material is issued to a job or schedule, or when resources, outside processing, or overhead is earned by a job or schedule. The same accounts are relieved when assemblies are completed from a job or schedule.

 
The Initial Mass Copy program populates the tax book from the corresponding corporate book. It copies all the existing assets in the corporate book.  You can create as many tax books as you need,
maintain your asset information in your corporate book, and then update your tax books with assets and transactions from your corporate book.

You cannot reinstate assets retired in the previous fiscal year. You can reinstate only the most recent partial retirement. You can reinstate both individual and mass retirement transactions. You can use Oracle Assets to retire a group of assets by populating an external interface table with these assets, setting the line status to POST, and running the Post Mass Retirements process.

You cannot retire an asset if you added it in the current period. Instead, you must enter your retirement as a prior period retirement after you run depreciation. Or if you do not want to create any journal entries, use Edit, Delete Record from the menu in the Asset Details window to delete the asset any time in the current period.

Asset is retired when it is no longer in service. For example, retire an asset that was
stolen, lost, or damaged, or that you sold or returned. You can retire an entire asset or you can partially retire an asset.
• When you retire an asset by units, Oracle Assets automatically calculates the fraction of the cost retired
• When you retire an asset by cost, the units remain unchanged and the cost retired is spread evenly among all assignment lines.

Suppliers are first created in header levels which are same for all the operating units. Next we create supplier sites specific to an operating unit. When we create a purchase order/invoice, we create it against a particular site.
