How to reverse a posted batch or journal entry on Sage 300 General Ledger

Steps:

Open General Ledger > G/L Transactions > Batch List.
Double-click the posted batch that you want to reverse, or that contains the entry you want to reverse.
The G/L Journal Entry screen appears, displaying the batch.
If you want to reverse an individual entry in the batch, select the entry in the Entry Number field.
Click Reverse. The Create Reversing Batch screen appears.
Select one of the Reverse options to specify which of the following you want to reverse:
- The selected entry only.
- The whole batch.
In the Batch Number field, specify the reversing batch to which you want to add the batch or entry you are reversing. You can create a new reversing batch or select an existing reversing batch.
In the Batch Description field, enter a description for the reversing batch.
- Note: If you created a new reversing batch, the default batch description is REVERSE BATCH, but you can change this.
Specify a description for each entry you are reversing. The method for doing this depends on what you are reversing:
- Whole batch. Select one of the Entry Descriptions options to specify a method for generating descriptions for the entries in the batch:
  - Original. Each entry in the reversing batch has the same entry description it had in
    the original batch.
  - Original with Prefix. Each entry in the reversing batch has the same entry description it had in the original batch, preceded by the prefix you enter.
  - New. Each entry in the reversing batch has the entry description you enter.
  - Individual entry. In the Entry Description field, enter a description for the entry you are reversing.
Click Process.
