XLA_AE_HEADER status Columns
 Table stores important status Information
GL Transfer Status Code (GL_TRANSFER_STATUS_CODE)
The GL transfer status code of the sub-ledger journal entry has one of the following values:
Not transferred
Selected to transfer
Transferred
When a sub-ledger journal entry is created and completed, the value of this column is Not transferred. The Transfer to GL process updates this column when the subledger journal entry is transferred to General Ledger.

Subledger Journal Entry Status Code (ACCOUNTING_ENTRY_STATUS_CODE)
A subledger journal entry can have a status of Draft, Final, Incomplete, Invalid or Invalid Related Entry.
Draft: The entry status is set to Draft when the following conditions are met:
Final: The entry status is set to Final when the following conditions are met:
Incomplete: The entry status is set to Incomplete when the following condition is met:
Invalid Related Entry: The entry status is set to Invalid Related Entry when the following condition is met:

The subledger journal entry is valid, but one or more of the other subledger journal entries associated with the same accounting event are invalid.
