SAP Message BRAIN187 - Selection element &1 contains too many rows

Diagnosis
In structure element &V1&, the characteristic &V2& is restricted to &V3&values. This number is very high and may exceed a technical limit. Ifadditional values are added, this can result in a termination (BrainA125) when the query is generated because the corresponding statementwill exceed the fixed size of 28K.

Procedure
Create an external hierarchy for the characteristic &V2& and merge theV3 values into one hierarchy node. then work with the node instead ofthe &V3& individual values.
Alternatively, you can define a corresponding navigation attribute byusing &V2&.
You can suppress this warning (Brain 187) for a query in the querymonitor (transaction RSRT) by choosing the Messages pushbutton orthe Edit -> Suppress Messages menu entry.
