The documentation says that the extractor 0EC_PCA_3 has a safety interval of one hour, which means that R/3 records "younger" than one hour are not being picked up.
My first question is: "Why is there this safety interval and why is it one hour?"
We kicked off 0EC_PCA_3 at 15:00. The delta load was missing some records that had been posted at 14:45. At 15:15, I ran RSA3 and it did contain those missing records. My second question is: "Does the safety interval become redundant if there has been another delta load between initial posting time and second delta load time?"
