Oracle Apps General Ledger (GL) KEY Tables GL_SETS_OF_BOOKS GL_SETS_OF_BOOKS stores information about the sets of books you define in your Oracle General Ledger application. Each row includes the set of books name, description, functional currency, and other information. This table corresponds to the Set of Books form. GL_IMPORT_REFERENCES GL_IMPORT_REFERENCES stores individual transactions from subledgers that have been summarized into Oracle General Ledger journal entry lines through the Journal Import process. You can specify the journal entry sources for which you want to maintain your transaction’s origin by entering ’Yes’ in the Import Journal References field of the Journal Sources form. For each source that has Import Journal References set to ’Yes’, Oracle General Ledger will populate GL_IMPORT_REFERENCES with one record for each transaction in your feeder system. GL_DAILY_RATES GL_DAILY_RATES stores the daily conversion rates for foreign currency transactions. It replaces the GL_DAILY_CONVERSION_RATES table. It stores the rate to use when converting between two currencies for a given conversion date and conversion type. Each row in this table has a corresponding inverse row in which the from and to currencies are switched. For example, if this table contains a row with a from_currency of YEN, a to_currency of CND, a conversion_type of Spot, and a conversion_date of January 1, 1997, it will also contain a row with a from_currency of CND, a to_currency of YEN, a conversion_type of Spot, and a conversion_date of January 1, 1997. In general, this row will contain a rate that is the inverse of the matching row. One should never insert directly into this table. They should instead insert into the DAILY_RATES_INTERFACE table. Data inserted into the GL_DAILY_RATES_INTERFACE table will be automatically copied into this table GL_PERIODS GL_PERIODS stores information about the accounting periods you define using the Accounting Calendar form. Each row includes the start date and end date of the period, the period type, the fiscal year, the period number, and other information. There is a one–to–many relationship between a row in the GL_PERIOD_SETS table and rows in this table.
