Count Not Zero Exception Aggregation with ABAP CDS View

0 Likes 44 Views 0 Comments

Count Not Zero is not among the options for ABAP CDS View exception aggregation, but if you really want it you can walk around this limitation.

Lets take, for example, C_StockQuantityCurrentValue (Current Stock Quantity and Value) CDS view. It shows all materials even the one without stock quantity and value.

What if you want to get a count of materials that have stock. Yes, it is possible combining formula and SUM exception aggregation together. For comparison reasons, I added another measure using COUNT exception aggregation.

// Count
