Hi,

I am working on a simulation and am struggling with filling an array.
Some background
* As first step I made a simulation of 1000 loans
* As a next step I have made a calculation sheet (Sim_bond_calc) to
calculate cash flows for each mortgage (the number of cash flows is
variable (parameter ‘i’ in my macro) / max 121 rows per loan). The
sheet uses the simulated loans as a starting point (parameter ‘h’ in
my macro)
* Now I am trying to create a macro that performs the cash flow
calculation for each simulated loan and stores the output in separate
tab. Since the number of rows may grow to approximately 121.000 I have
chosen to use an array function.

I am struggling with filling the array properly:
• First I have tried to loop through the calculation sheet and write
the results to the array. This is shown in Macro 1 below. The macro
does only store the results of the last loan (number 1000)
• Next I have tried to copy all cash flows from the calculation sheet
to the array (macro 2) but whatever I try I get a run-time ‘1004’ –
Method ‘Range of object’_Global’ failed error.

I hope someone can help me!

Kind regards,

Paul
