Hi Andrey,
even with access to the delta buffer it would be hard (I think impossible) to implement a new lines check.
1. You would need the data the query has read, possibly by reading again the data the query has read (vial plan buffer access). This is in general not possible since the query has much more filtering featues compared to the plan buffer (e.g. restricted key figures).
2. You would need a delta buffer access (but this is not exposed via an 'external API'), but this is not enough since the delta buffer does not care whether a record is new or old. One does not know this in the delta buffer.
To implement a real new line check (only 'real' new lines are allowed) one needs the old result set; this is not even known to the OLAP since e.g. for drill-down only the needed data will be read, not the full grid the end user sees in the front end. In the 7.0 code line this information is simply not there.
With the new infrastructure shipped in 7.01, SP05 (cf. note 1358614) a kind of new lines check in the above sense would be relatively easy (for SAP) to implement. But one question is, what is a new line, think of zero suppression, conditions ? Should the system take records into account filtered out by the above featues ? Should a new line check by a query property ?
