Prevent particular field from getting updated from flow designer

[Ayushsnow]

Hi all,

I've a requirement to populate planned start/end date on the child form .These two field will be same as entered manually in parent. For this I've created a business rule(after insert on child table). For first few second it is taking the right value(that means what we are putting in parent) but after that due to the flow designer(where some calculation is done)the field is getting modified. I want that my business rule runs when we enter planned start/end date manually in parent form and post that the flow designer is not able to update that field. Also keeping in mind if two fields are 'not entered'/empty, then the flow designer will do its calculation and update the fields.

Is there any way I can prevent other scripts/flows to update the field once my business rule runs?

in flow check if both the fields are empty then only do the calculation and set the value.
