Hello Louis Ewango,
Couple of things.
--- Is that logical to display the same customer balance in both sides of balance sheet based on debit and credit values as recorded?
--- Is that same customer is a vendor as well?
Whatever is receivable and payable to the customer; will be adjusted in the customer balance itself and the summarize value will display in balance sheet.
If I am not wrong; I don't think it is possible to cater such requirement to display in report.
Alternatively; you can do the following;
--- If the same customer is a vendor too, then create a separate vendor account with the same customer details and set this vendor in the remittance vendor account field available in the customer master form.

--- Next go to Global address book; filter by name of this customer and vendor (as name will be same) and merge both party IDs. You can select the customer party ID to retain before merging. You will get the option there.
Therefore; you will get both Debit and Credit balances for the same customer (who is a vendor too) and it will be available in both sides of the Balance sheet as Asset and Liability.
Kindly review and provide your feedback.
Best regards,
Sourav Dam
