Calculate expected customer lead time

Hello Team,

It has been a lot of time I am trying to create this measure but have not gotten an expected result. I came here with lot of hopes

Have a look at below table

The above table is a replica of my power bi file, where I am trying to calculate the Lead Time column.

Below are conditions and calculations.

1. if On-hand Quantity is "0" or positive, Lead Time will be "0"

2 If On-hand Quantity is Negative then, it should show the count of weeks to wait to get On Hand Quantity equal or greater than the sum of Receipt Quantity starting from next week.

Example 1:- how 2 is there in Lead time column in week no 2?
 On hand quantity is -30, so let's start suming up Receipt Quantity values from next week that is 3 , if you sum week 4 and 5 Receipt Quantity values then it gives 30 which is equal to 30(Ignore Negative sign) in On Hand Quantity at week 2, So Lead time column shows count of weeks to wait, here it is 2 (week 4 and 5)

Example 2 :- How 10 is calculated in week 7?

 On hand quantity in week 7 is  -150, so let's start suming up Receipt Quantity values from next week that is 8 , if you sum week 8,9,10,11,12,13,14,15,16 and 17 Receipt Quantity values then it gives 200 which is greater than -150(Ignore Negative sign) in On Hand Quantity at week 7.
