Hi all,
I am trying to calculate week over week inventory - this is what my data currently looks like:
But I need the end inventory to be the starting inventory for the next week like this:
Thanks in advance!!
Hi @Anonymous ,
Create a separate Dates table (if you don't have one yet) and use the week start from that table in your visuals. Then create this measure.
Start/Opening inventory =
CALCULATE (
MAX ( data[ending inventory] ),
FILTER ( ALL ( datestable ), datestable[week] < MIN ( data[week] ) )
)
Please refer to attached pbix files for the dates table and sample calculation of opening balances.
Hi - thanks for the response! I am getting this error:
Not sure if this helps, but my starting, change, and end inventory are all measures not a column. All of my tables are connected by date.
