I need to use a manual data entry via excel spreadsheet and have found that via SDK buffering, data can be fanned to multiple collective members. I have following questions on this:
1) Can the data be over written? or it has to be deleted first?
2) Have herd that incase the old data needs to be deleted, we need to delete it individually on each PI server? Is this going to get overcome in any new latest versions or is there any workaround? Also when we are deleting manually, is it manadatory to close down PI buffer subsystem?
3) Does manually entering data, writes values directly to archives wothout entering the sanpshot queue? In this case would the PE equations which are event triggered by these values fail to trigger? since they take events from snapshot?
