Jinjia question

You are not incrementing the adate counter , try below

{% set adate = adate + time.delta(days=num) %}

Optional
time.today will generate date at utc time . Using time zone help , I generally do 

{{ (time.now|timezone('Asia/Calcutta'))|date_ymd('-') }}

Hope this helps.

All thanks @Quick Base Junkie for awesome jinja training

Hi, this code is based in your original code, this work for me:

{
    "to": "btk9drq7t",
    "data": [        
        {% for num in range(5) %}        
        {% set adate=time.today+time.delta(days=num+1)%}  
        {        
            "6": {
            "value": "{{adate|date_ymd}}"
            }
        }
        {% if loop.last == false %},
        {% endif %}
       
        {% endfor %}
    ]
}

Thank you

Just give a quick update.

By using namespace function as Prashant 's instruction, I am able to calculate each total within each cycle and assign the value to the child table.  Thanks again for Prashant's post.
