Issue with 0FI_AR_3

We are using 0FI_AR_3 extractor and for some reason it did not pick up records which were entered for a short period of time (about 3 hrs). We have documents which were entered in the monring and the evening for the same day. Did anyone experienced this where the extractor failed to fix documents which were created on the same day. These are similar documents with the same posting key. Please give me a guidence on where to go and see.
