Thanks for your input Kaspars
I've exported the table 7154 to excel and compared the same item number 20002 from above.
In table 7154, the only difference I see is that there are some additional entries from 2022 and 2024, while the sales analysis view export was filtered to 2023 sales only. Otherwiese the two excel tables match.
I noticed, while scrolling through the item card postings, that in August there were two sales orders for the same customer and same delivery date. I suspect these were invoiced together. these two sales quantities 40 and 20 pieces are combined in the sales analysis view as 60 pieces in August. But there is a second entry for 30 in August which was another customer at a later date.
The sales analysis view does combine all sales by month in the matrix view within BC. if I click on the August 90 number, I see a list of two postings 60 and 30.
Unfortunately "related > actions > export to excel" does not keep the monthly consolidation but shows both postings.
If I export to excel using the share button, I get the monthly consolidation, but the table format is the same as the sales view matrix with columns for each month.
Ultimately I want to get the format with the item and month as 12 or less rows, in hopes of importing this somehow back into BC as a forecast.
Side Question: could I import as a forecast in its existing state with multiple quantities at the same date? Continuing from above, August 01 has two entries 60 and 30. Would the forecast import recognise both quantities? I've found table 99000852 Demand Forecast Entry, which I can export and view forecast entries. But how can I import from excel back to BC?
Many thanks!
