I´m trying to calculate plan accuracy where I can "use" orders from +-1 week to fulfill the plan. As you can see in the image below I have 13 weeks. In those 13 weeks I have plan in column C and orders in column B. Columns A, B and C are my data, the rest is what I want to calculate. In column E I have calculated the Orders +-1 week but taking into account if there are any leftover from previous period. The problem is that the leftover are reliant on Orders +-1 week. This is possible in Excel because in the Orders +-1 week (column E) I reference leftover (column F) from the row above. So the leftover formula for line 3 is E3-C3 and the Orders +-1 week for line 3 is B4+IF(F2>SUM(B2:B3),SUM(B2:B3),IF(F2>0,F2,0)).
In Power BI it´s not possible to reference a column/measure that relies on the source column/measure.
The goal are column G, H and I using only columns A, B and C. So my main goal is column H line 15 (the total accuracy) but I would like to calculate accuracy pr. line and covered batches as well.
The datasource is not Excel and not in this exact format but it´s reprecentative of the data source.
If anyone has an idea about how to go on about solving this in Power BI I would be very greatful. I don´t care if the solution is in Power Query or DAX. You can download the Excel file with this example and another one here: https://tinyurl.com/4b55kaxh
I have just fiddled a little with it in Power BI so I don´t have any PBIX to share.
Good try but unfortunately not what I need. I have come to the conclusion that it´s not possible (at least with my knowledge) so I´m not going to calculate it in this way. I going for a less accurate but good enough method of looking at the total period instead of focusing on each week.
