We are using SAP - ISU BW extractor 0FC_BP_ITEMS and its related DSO (Open Items ZFC_DS06 & Cleared Items ZFC_DS07).
These DSOs have become huge in data-size since these are being filled since 2011. The data flow diagram is as follows:
DSO ZFC_DS05 -> Open Items DSO : ZFC_DS06 -> Open Items InfoCube ZFC_C08
-> Cleared Items DSO : ZFC_DS07 -> Cleared Items InfoCube ZFC_C09
The question is, can we safely delete change-log entries of DSO ZFC_DS05 and further DSOs ZFC_DS06 and ZFC_DS07?
Will it have any impact on delta data flow w.r.t. key figures from 1st level DSO ZFC_DS05 to 2nd level DSOs i.e. Open Items ZFC_DS06 and Cleared Items ZFC_DS07? Kindly share your inputs.
