Processing data in matrix - iterative loops through data fields

I hope someone can help me out with a particular problem. After several days processing data in a matrix form i am now stucked with it.

We have multiple products within multiple storages, and a list of orders, when (on which day) we have to deliver these products.

The warehousing is working with FIFO principle. If the oldest storage is out stock, we pick from the next later storage and so on.

I have to calculate now, from how many storage does a single product of one order come from. I have tried working with tranpose, crosstab and multiple rows, multiple fields but haven't successed jet. Below you can see the simulated datas. Ofcouse we have more then 6 storages and much more than 2 products.

Warehose Data

Object-Nr.	Storage place	Date of receipt	Stock
1111	A1	01.01.2020	100
1111	A2	02.01.2020	100
1111	A3	03.01.2020	500
1111	A4	04.01.2020	300
1112	A5	01.01.2020	350
1112	A6	01.01.2020	200
