Understand Why Some Transactions are Blocked, Locked or Cannot Be Modified

Here are the circumstances that can make a transaction unmodifiable

1. You do not have the necessary rights to modify transactions:

   In this case, you must ask an administrator to give you the necessary rights.

2. The transaction is in a closed period:

   In this case, you must cancel the period associated with the transaction date.

3. The transaction is associated with an invoice from the sales module:

   In this case, the transaction must be modified via the sales module.

4. The transaction is associated with a purchase order from the purchasing module:

   In this context, the transaction must be modified via the purchasing module.

5. The transaction is an invoice to which a payment has already been applied:

   In this case, the payment must first be withdrawn.

6. The transaction is a payment linked to a cheque, direct deposit or pre-authorized payment:

   In this case, the payment must be deleted beforehand.
