Bug report

The following problem occurs when trying to make a customer return from the point of sale, since having or having mounted an order which was completed, and generated its invoice when it was located again to generate a return with the process "Cancel Sales Transaction "this throws a message of" Request failed with status code 404 "closes the order at the document status level but does not generate the" Customer Return Order ", the" Customer Return ", and the" Credit Note of CxC Pos "

Steps to reproduce

To verify this case, the following steps must be performed:

1. Create a new order either from the point of sale "USD" or "VES"
2. Associate "Client"
3. Associate "Product"
4. Add charges and process "Order"
5. Verify that the order is in "Complete" status
6. If the order is in a complete state, locate in the quick options of the point of sale the option "Cancel Sales Transaction" and apply to the order that was made.

Expected behavior

The expected result for this case is that when you already have an order mounting in ADempiere and you want to cancel it for a return, this when being located and applying the "Cancel Sales Transaction" process must carry out the following steps:

1. Close the order where the sale of the product (s) that the customer bought had been mounted.
2. Generate a Return Order in the "Return Order (Customer)" window which must show the same products and the same order quantities.
3. Generate a customer return in the "Customer Return" window. This is what actually returns the products that are being returned to the warehouse.
4. Generate a "Credit Note" in the "Documents Receivable" window and associate it with the fiscal invoice of the sale that had been made to the customer.
5. Generate the counter-items of the charges that the customer had made when the sale was made.
