COPA delta

Hi,

We have COPA safety delta set to default of 30 mins... but when we run COPA delta, it is found that transactions posted before 30 mins in R/3 COPA are not pulled.

Sometimes its takes more than an hours times for the R/3 COPA data to be pulled in BI.

We have R/3 and BI on same time zone.

ROOSOURCE-DELTASAFE2 is set as 1800.

What could be the reason behind this and how can i minimise the safety delta to min ... 5 mins.

Please help.

Rgds.
