How to update task start date when project start date changes?

How to update task start date when project start date changes?

Hi there,

When the start date of a project changes, it's important to update the start dates of the tasks associated with that project to reflect the new timeline. 

Is there a way to shift the start date of all project tasks when the start date of a project changes.  

Ive been trying to create a custom function for this but without any success.
Tried to do this with a Zoho Flow but fetching task lists and task in flow is not really workable solution. 

Any help will be very much appreciated.

      Though we move from the traditional project management system (using papers) to an online project management system, we still prefer to have a printed copy of the activities/tasks that are to be done in the project. This way, we can carry the to-do lists with us for the meetings and refer when we are offline. The print option, available at the right side of the page, allows the users to print the project information across all the modules. However, this option failed to print all the tasks & milestones

    • Task Inline Editing Enhancement

      Hi All, Today, we have made an enhancement in task inline editing. In 4.0, task edit is moved in a single screen in a pop-up. We designed this in-order to make the task edit across the product to be the same. Let it be in Feeds, Tasks & My Tasks tab, Calendar & My Calendar tab, a click on the task title will open the popup and user can edit the values. Customers pointed us the inline editing was very useful to them & how much they miss that in 4.0. Based on the feedback, we have rolled out this enhancement.
    • Blueprint in Zoho Projects

      Often, we stumble upon tasks having the same status workflow. Repetitive task processes are tedious to handle, right? That’s why we have introduced Blueprint for task automation. Blueprint is a tool to organize tasks and automate them based on the workflow you design and the criteria you define.    How do I associate tasks with a blueprint? You can set the criteria while creating the blueprint such that when you publish a blueprint, the tasks that satisfy the criteria will be associated with the
