Hello,

I am working on creating a Weeks of supply calc that would be a loop within
VBA and I am hoping I can get some help here. Below is a sample table.

Item OH Wk1 Wk2 Wk3 Wk4 Wk5 WOS
1 6 2 3 1 0 0 ?
2 10 1 4 3 2 5 ?
3 8 1 2 4 3 1 ?


In the table above, I have the current OH for each of the items listed. The
calculation for weeks of supply would be calculated in that the current OH -
each number to its right until it hits 0. Example, item 1 would have 3 weeks
of supply. Item 2 would have 4 weeks of supply. Item 3 would have 3.3 weeks
of supply.

Any help on VBA for this would be greatly appreciated.

Chris

assume 1 6 2 3 1 0 0 is in row 2 starting in A2, then in H2 put the formula

=if(sum(C2:G2)0,B2/Average(C2:G2),"--")

then drag fill down the column.

This doesn't produce your results, but uses the average demand per week.
You would have to show how you come up with you values. I get
5

Tom,

Thanks for the response. Maybe the format I pasted in did not come out
correctly.

For a stimge item, the current OH is 6. The sales forecast for futre weeks
would be Week1 2 units. Week2 3 units. Week3 1 unit. The result I am
looking for is for VBA to run a loop so that it takes the current OH and
consecitively goes through and takes the future weeks of sales away until I
hit zero. Then count the # of weeks for this to occur. This example, I own
6. after selling 2 units it will be 4, then after the 2nd weeks when I sell
3 units, I have 1 left. The 3rd week, I would sell the last unit. Hence I
currently have 3 weeks of supply.

I have a sample of VBA for this, but I did not write it and it current tries
to pull OH from another Database, which I do not need. I will post it below:



Sub HIGH_WOS()

'Adding 9 to MySize1 simulates the y variable starting at 9.
TtlSales = TtlSales + Cells(x, y + z).Value
