How to change a Project level Funding to a task level Funding?

Hello,

We are funding our projects using Oracle Grants.

For the award, we have created a project funding at the project level and created a budget with task level details.

Now, we want to change the Funding to task level, but the task field is greyed out for that project, even when we are adding new funding lines.

1. Can the Funding be changed from project level to task level?

2. If not, what repercussions can we have later as we have done the budgeting at task level?

Thanks,

Khushboo
