how to refresh an incremental cube in microstrategy between two dates by replace option

Question

while we are trying to refresh an incremental cube daily using refresh option "replace" and for last 7 months filter which is defined as Postgresql statement using applysimple command:

"SELECT TO_char(current_date-INTERVAL '7 months','yyyymm')::numeric"

This filter gives the following error:

"Error: Invalid logical functions used in filter. Filter functions can only be Equal, And, Or and Not.

Error in Process method of Component: QueryEngineServer, Project XXXX, Job 3648, Error Code= -2147212264."

How can we handle this dynamic refresh logic? Thanks

Answer 1

Incremental Cube Refresh object does not allow usage of ApplySimple method for updates using "replace" method, the filter has to be created at Public Objects > Filters and for creating a time filter, a driving attribute of the report (if the report is about orders, an attribute like "order_date" ) should be chosen.
