@manal_erpnext I doubt it . there must be the same name

[manal_erpnext]

that message is appear

[manal_erpnext]

@bahaou

is this the matter?

[manal_erpnext]

when i change the value in yellow the change applied in the blue place

[Yamen_Zakhour]

Your document naming rule is set to autoname based on the field customer_name.

Meaning;
When you create a new customer doc, the value of customer_name will be assigned as the Document Name (doc.name)

However further changes on the field customer_name will only change the value of that field but not the actual document name.

[manal_erpnext]

okey but why i get that message when want to change the data?

[Yamen_Zakhour]

It seems you are not in prod, so delete all customers and try again.

[manal_erpnext]

when delete all the data and sill be in this mode it will work?

[Prasant_Pant]

please change the naming rule to empty or somthing.
`

Remove the : By fieldname and empty the auto name.

`

it will work

[manal_erpnext]

@Prasant_Pant
when i try this and save this is the result

the auto name could not be empty

[Prasant_Pant]

if you have created the doctype , you can directly edit the doctype instead of customization.
I think you can do it there.

[manal_erpnext]

the customer doctype is build in

[Prasant_Pant]

use this

[manal_erpnext]

i want the naming by the customer name itself

[Prasant_Pant]

Then Customer name must get unique. After which you cannot able to create duplicate name.
