Viewing R/3 Table and Structures 
Use
You can use the SAP Assistant table browser to view the metadata of an R/3 table or an R/3 structure.
Prerequisites
You must know the name of the table or structure.
Note that viewing a table or structure is not related to browsing BAPIs or RFCs, and therefore it is not related to any activity in the BAP/RFC browsing area (in the three panes of the browser)
Procedure
Result
The Table/Structure Browser dialog displays information about the various fields of the R/3 table or structure.
You can change the size of the columns in the Table/Structure Browser dialog.
Dismiss the dialog by choosing Close.
