I take this to mean a reference code or part number that only a particular customer uses which may be different to it’s normal item code or supplier code (if it has one)
Its a field used to track the customer’s item code. It doesn’t automatically appear on sales invoices, but you can customize the forms to make it appear.
This is used when the customer wants a supplier to use their item code reference instead of supplier’s in the sales/purchase documents.
I want to use this customer details section as for the limitation of items in PO SO SIN ect
like when i have selected the customer in Sales order only items should be display where customer is selected in the item form. im using this script but problem is only 1 item is comming and i have selected this customer in multiple items.
