I'm working on customized module that added analytic account field in stock.move model and it also add this field into the journal entry but it added it on the debit line. I need to add the analytic field on credit line please, this the code from the module

class StockMove(models.Model):
_inherit = "stock.move"

analytic_account_id = fields.Many2one(
    string="Analytic Account", comodel_name="account.analytic.account",)

def _prepare_account_move_line(
    self, qty, cost, credit_account_id, debit_account_id, description):
    self.ensure_one()
    res = super(StockMove, self)._prepare_account_move_line(
        qty, cost, credit_account_id, debit_account_id, description
    )
    # Add analytic account in debit line
    if not self.analytic_account_id or not res:
        return res

    for num in range(0, 2):
        if (res[num][2]["account_id"]!= self.product_id.categ_id.property_stock_valuation_account_id.id):
            res[num][2].update({"analytic_account_id": self.analytic_account_id.id})

    return res

@api.model
def _prepare_merge_moves_distinct_fields(self):
    fields = super()._prepare_merge_moves_distinct_fields()
    fields.append("analytic_account_id")
    return fields
