Hi
I have a query that shows part numbers with a total qty ordered for a specified time period. This first part of the query is fine and is made into a table.
I am then trying to use this table to create a running sum with the list sorted in descending order, and ultimately break the list where the sum reaches 80% of the total qty across the whole list. I have tried the following formula and the table has been indexed in the descending order it would need to be in. The IndexAlias has also been created and made into a fixed table prior to running the 'Running Sum' query.
RunTot: DSum("qty_ordered","Core Stock","[Index]<=" & [IndexAlias] & "")
I have taken this formula from the microsoft link below, (Method 2), and adapted it to my query. However, although I have a decent understanding of Access I do not understand the '&' in this formula. Removing this and the double quotes on the end returns an error and leaving them in returns zeros all the way down the 'RunTot' field. If anyone can help I would appreciate it as I am stuck on this.
