Missing Delta data with DataSource 0UC_INSTFACTS
We load the data from DataSource 0UC_INSTFACTS (Installation Facts) into DSO 0UCS_DS06 and it is extracted through the Function Module ISU_BW_INSTFACTS_GET_M_DATA. It gets the data from ETTIFN table. This datasource is capable of handling delta and it could be found in ROOSOURCE table. I could see the data in RSA3 & RSA7.
We have more than 75 millions of records in ETTIFN table in R/3 and we have just 2 millions in DSO 0UCS_DS06. Now we have found that the DELTA loads which completed successfully DIDN'T load all the records completely. We didn't set any filter, but somehow a lot of records got skipped while loading into BW.
Do I need to set up any settings for Installation in the IMG to capture the records?
Is any one has encountered this problem with datasource 0UC_INSTFACTS?
Thanks in advance.
