FI Data source functionality in back ground
for me few doubhts are in BI data source Level ,
In BI Data source we have Direct access types.
In that three different direct access type are there mentioned below
*1-supported (without preaggregation)
*2-supported (with preaggregation)
*D-notsupported means it wont support direct access
Remaining two what is that preaggregation and without preaggregation .
Preaggregation meas direct access could be used for reconcillation of datasource with selection they have explained I couldnt get the exact meaning what they are telling....
table BWOM2_TIMEST--is having the entry of datasource name which wont support direct acces.In Case of 0_FI_GL_10 its not having any entry in BWOM2_TIMEST because it supports direct acces so its respective table is capturing the time stamp......why its getting diffferent from datasource to datasource like some supports direct acces and some wont support direct access .......what is happening in back end really confused with this ....
Searched for documents I couldnt find so please share some documents regarding to this if you have
