Diagnosis
If queries (often unintentionally) are assigned the read mode "Query toRead All Data at Once", this often results in performance problems. To e
liminate this problem, this warning is displayed when you execute aquery with this read mode when the query is generated.

Procedure for System Administration
Before you execute the query, repair the read mode:

• You can repair the read mode for this query in the Query Monitor
(transaction RSRT1). You can set the read mode for the selected query by
choosing Query -> Read Mode.

• If this warning is displayed when you check a query, you need to change
the default read mode for new queries in the InfoCube in InfoCube mainte
nance. In InfoProvider maintenance, choose Environment ->InfoProvider Properties -> Change and make the relevantsettings on the Query/Cache tab page.
