I have another question
1. How can you reverse an IN posted batch. How can you correct it if you see that you have posted but there is an error
2. What about the Customer Cash book batch
Thanks George
The only way to reverse a posted AR Journal batch (or AR Standard Transaction) is to do the following:
1. Inspect the relevant IN transaction type that was used in terms of the specific GL accounts that was used
E.g.
2. Now inspect the CN transaction type (AR | Maintenance | Transaction Types)
Ensure it has the same GL accounts but in the opposite posting orientation as the IN transaction type
E.g. If the Receivables Control account is debited in the IN transaction type, then the Receivables Control should be credited in the CN transaction type
3. When satisfied, you can now capture and post new AR journal batches by using the same customer accounts, transaction dates etc, and the CN transaction type,
Unfortunately it remains a manual process and there is not a quick reverse batch feature in Evolution to accomplish it.
However, also perhaps consider restoring a backup that was made directly after the AR batch was posted, and then re-capture other transactions as required
My pleasure, George!
