How to find the table size in SAP system from SAP GUI

1. t-code DB02 -> Space -> Segments -> Detailed Analysis -> enter values into fields:

Segment / Object = table name

Type = TABLE

2. t-code DBACOCPIT -> Space -> Segments -> Detailed Analysis -> enter values into fields:

Segment / Object = table name

Type = TABLE

3. ABAP report RSTABLESIZE. On it selection screen just specify table into field "Table Name ". Notice this doesn't work for BW objects e.g. starting with prefix /BIC/* for which do DB statistics wasn't calculated yet.

4. Table DBSTATTORA which displays actual size of tables on the database. Just enter the table name into the field TNAME. Table size is shown in field OCCBL - Used blocks of a table in KB. Again to have this value in the table DB statistics must be up2date.
