My client used some third party software to copy invoices from production system to sandbox. This didn't copy the GOS attachments to the sandbox.
My requirement is to move the GOS attachments from Production to sandbox.
Copied invoice 8000541 from production to sandbox. It created a copy of that invoice to 8000530 (Different because of the number ranges). Now i want to read the attachments content from production and tie them to the related invoice in sandbox.
How can i do this?
