Hi,

If your data is static, you set up the same in default value.

Else, you can set the value via Server script on submit.

Hi,

You can do it with below code:

import frappe
from erpnext.accounts.general_ledger import GLEntry

class CustomGLEntry(GLEntry):

    def before_insert(self):
        
        self.transaction_number = self.get_next_transaction_number(self.transaction_type)

    def get_next_transaction_number(self, transaction_type):
        # Get the last transaction number for the given transaction type
        last_transaction = frappe.db.get_value('GL Entry', 
                                                filters={'transaction_type': transaction_type}, 
                                                fieldname='transaction_number', 
                                                order_by='transaction_number desc')

        if last_transaction:
            # Assuming transaction numbers are integers, increment by 1
            next_transaction_number = int(last_transaction) + 1
        else:
            # If no previous transaction number exists, start from 1 (or any other base number)
            next_transaction_number = 1

        return next_transaction_number
