Cannot close AR period due to one incomplete adjustment number showing on the subledger period close exception report.

You have to either Reject/Approve the Adjustment or change the GL Date to resolve all the adjustments prior to closing period.

To remove adjustment from subledger period close exception report:
1. Sign into AR responsibility and navigate to Control > Adjustments > Approve
2. Query adjustment number and either approve or reject this adjustment.

a) If adjustment is approved then run create accounting to process this adjustment. This adjustment will no longer show on the subledger period close exception report as incomplete.
b) If adjustment is rejected then this adjustments will no longer show on the subledger period close exception report.  The subledger period close exception report does not display rejected adjustments.

If the adjustment cannot be approved or rejected before period close then you have two options:

1. Set the next period status to Open or Future and change the GL DATE of pending adjustments to next period.

2. If the next period status cannot be changed to Open or Future then set the current period status to Pending Close.
Whenever the next period is opened, change the GL DATE of pending adjustments to next period and change the period status from Pending Close to Close.

However, before changing the period status to Close Pending ensure that:

a. There are no unposted items other than pending adjustments.
Run the Unposted Items Report and Subledger Period Close Exception Report.

b. Run the Revenue Recognition Program to process ‘Invoices with rules’.
