Hi Srinivas,
You can use the view WB2_V_VBAK_VBAP2 for fetching data from VBAK and VBAP instead of using a JOIN. Note that, in the view, item data fields will have a I following the field name (POSNRI, MATNR_I are the item data fields from VBAP). The master data fields of VBAK are the same.
As far as i know, there are no standard views provided by SAP for VBEP and VBBE. Not sure if FM exists either.
While using FOR ALL ENTRIES clause make sure that you specify the entire primary key (EX. if selecting from VBAP specify VBELN and POSNR) as fields for selection or in the selection criteria. Its much better if you have the primary key in both. This is really important because without specifying the entire key and using FOR ALL ENTRIES will drastically bring down the performance. And also, If you are fetching not more than 100 or 200 entries using the clause it is fine, beyond that its same as using a select statement within LOOP...ENDLOOP.
So, you have to decide whether to use FOR ALL ENTRIES or a JOIN while selecting data depending on the requirement. If you don't have the entire key either in fields for selection or selection criteria, then its better to use a JOIN or VIEW.
The following is an example for using FOR ALL ENTRIES clause effectively.
         Select VBELN
                    POSNR
                    MATNR
            From VBAP
              into Table T_VBAP
          For All Entries in T_DATA
          Where VBELN eq T_DATA-VBELN
              And POSNR eq T_DATA-POSNR.
I hope this helps, Please let me know if you need further assistance.
