List of all infoobjects & it's table where we can find it's length/size

Hello,

Is there any table in SAP BW which will give me the infoobjects along with it's size/length, data type, etc.?

I was searching through various threads and I didn't find any table which will give the information which I was looking for.  Even the table RSDIOBJ doesn't have any such information which I'm looking for.

This would help me in developing models easier and faster as we need to search every time from RSD1 tcode to get it's properties.

Kindly suggest.

Regards,

Antony Jerald.
