Hi Dilshan,
Try this:
Create a copy of your ORDER CYCLE LT (I assume that it is a SELECTION not a formula), let's call it ORDER CYCLE LT-COPY..
In the ORDER CYCLE LT-COPY, add the characteristic SALES ORDER TYPE..Right click the object SALES ORDER TYPE and choose CONSTANT SELECTION..
Then in your formula ORDER CYCLE LT TOTAL, do this:
ORDER CYCLE LT / ORDER CYCLE LT-COPY
