Can I Add all the fields from POOL to EXTRACT Structure in LBWE

Question

Dear Experts,
Our Client is asking to add all the fields in the POOL Table to EXTRACT STRUCTURE in LBWE that is he wants to add all the fields from Right Hand Side Table to Left Hand Side Table in the Maintenance of LBWE of all the SD Data Sources. For few fields there is no data even though they are saying that in the nearer future we are going to use all most all fields.
Like wise they are asking to add all the tables like VBAP, VBUP, VBAK, VBKD, VBUK, etc.,
My Questions are:
1.Is it advisable or recommended to add all the fields from POOL to Extract Structure because client desperately needs them.
2.Is there any performance issue when we add the fields from POOL to Extract Structure at the time of extracting data from R/3 to BI.
Regards,
Sai Phani

Hi Sai,
1.Is it advisable or recommended to add all the fields from POOL to Extract Structure because client desperately needs them.
we can add all the fields from the POOL to Extract Structure, if really your business requires to pull all the data.
2.2.Is there any performance issue when we add the fields from POOL to Extract Structure at the time of extracting data from R/3 to BI.
Ofcourse, there will be performance matters, because we have to extract maximum number fields data to BI side. If we have data for all the fields in R/3, we may face performance problems like load takes long time.
Hope this helps.
