Allocation Cost to days based on allocation rule

Hello Community!

I would need some tips to get my allocation problem solved properly.

I have a project with start date and end date. Then I have predicted costs and then an allocation rule that says for example that project is split into 4 splits (based on duration end date - start date). First step gets 10% of predicted cost, 2nd step 20%, 3rd step 20% and 4th step 50%. Cost should be allocated for each days, for example 10% of total cost should be allocated to days in the first step.

Example data:

ProjectID; StartDate; EndDate; AllocationRule; PredictedCost

ID1; 1.1.2019; 20.5.2019; Rule1; 100000€

AllocationRule; Allocation1; Allocation2; Allocation3; Allocation4

Rule1; 10; 20; 20; 50

Any Idea how this should be done?
