I would need some help in finding an expression for accumulating values in a pivot-table, where the leading dimension is used as "x-axis". Unfortunately the typical approach with rangesum and above does not work anymore, once the dimension is shown horizontally. I also tried adding TOTAL without success.
As you will find in the enclosed example-file the formula works, when the dimension ("Period") is used vertically. But as those are e.g. weeks and the other Dimension ("Id") has a lot entries with long names I would like to use them in the described way.
In the example-file is also a possible solution, but I would like to avoid to copy the same formula 50-times into the same diagram. - Do you have ideas, how to solve that in a more elegant way?
Re: RangeSum-Above-Combination in Pivot-(Cross-)Table
Just to complete this topic ...
Finally I went a totally different way after the application got some bad performance problems with my 7000 x 100 table. Furthermore I had to change the formula, depending on its usage (diagram/pivot table/sum table) what wouldn't really help in maintenance...
I made a very small extention in my load script, which helped for all cases... The example is attached.
