Table /BIC/B0* or /BI0/B0* with big size in transaction DB02 or EWA report
Cause
/BIC/B0* or /BI0/B0* are PSA table or the changelog table of DSO.
It becomes bigger if dataloading is scheduled.
Resolution
Firstly, identify if it is PSA table or change log table.
• the way to identify: go to t-code SE16 -> table RSTSODS -> input the table name into field
ODSNAME_TECH (description: Technical ODS name) and Execute.
Normally, if it is changelog table, the relevant DSO name can be found from field ODSNAME (description:
Persistent Staging Area) field.
If it is PSA table, the relevant datasource name can be found from field USEROBJ (description: Object
Name) field.
• the result can be verified: in t-code RSA1 -> click "Find" from Modeling panel -> input the value of field
ODSNAME or USEROBJ, choose Object Types as "datasource" "datasource 3.x" and "DataStore
Object (classic)", then click Search. Double click the displayed result and check if the it is DataSource
