Columns in XLA_AE_HEADERS and Transfer Status

What columns in XLA_AE_HEADERS indicate the Transfer Status of accounting data in subledger?

The XLA_AE_HEADERS table shows the transfer status of the accounting data, after successful transfer to the GL and Journal Import:

XLA_AE_HEADERS.gl_transfer_status_code = Y
XLA_AE_HEADERS.gl_transfer_date is not null
XLA_AE_HEADERS.group_id is not null

For 11i data upgraded to R12, the transfer status can be determined using the following

XLA_AE_HEADERS.gl_transfer_status_code = Y
XLA_AE_HEADERS.gl_transfer_date is null
XLA_AE_HEADERS.group_id is null
XLA_AE_HEADERS.upg_batch_id is not null  –> indicates 11i data
