How to set default aggregation using only local annotations file?

[boolan]

Hello,

I am writing an Analytical List Page application on NW 7.4.

I need to display a pie chart in which I want to display aggregated values.

The dimension is sales organization.

The pie chart is displayed, but it does not show the accumulated values, just the values from the first row of the sales org.

I suppose I have to indicate that the measure should be aggregated.

In CDS view I would annotate the measure field as:

@DefaultAggregation: #SUM

But how to achieve that using only local annotation file in WebIDE?

I cannot modify the gateway service.

I found the following annotation: Analytics.AccumulativeMeasure which can be true | false.

But it can be set in different places and so far did not work for me.

Any ideas how to make the donut or pie chart accumulate the values using only local annotation file?

Many thanks and best regards,

Krzysztof
