i have spent 40 hours, and still didn't find a solution. Please help is need it!!
example:
i have to find all articles with same code (222). first one has Q =100 second one Q=250.
soled Q=150
(i am talking about 5000 rows, 400 different or same articles per month- 12 months)
columnA-----columnB---columnC
222 ----------100---------0
111-----------50
333-----------70
222----------200---------200
333---------- and so on
first i have to deduct from the first one it finds (max. till 0 ...it can not be negative) ....after finding another one it deducts the rest---it means 50
Is there any kind of formula with this possibility.
if it is poorly writen please let me know for more info.
i am not an expert in excell, but i have tried variations of sumif, vlookup functions, but i always get stuck deducting the whole Quantity from all of the same (222) articles .
thank you for your kind help
