Populating Additional Field in InfoSet Query

Question

Hello,
My team and I are working on generating a relatively simple report from the VBAK (Sales Header), VBAP (Sales Items) and VEDA (Date data) tables.  We would prefer to be able to build an InfoSet (SQ02) and Query (SQ01) instead of writing a custom report.
The problem is the VEDA table contains data that may link to the VBAK and sometimes the VBAP table.  The usage is that the header has begin and end dates for a contract, which is denoted by a blank value in POSNR field in the VEDA table.  If a particular line on a contract has different dates than the header, there will be an additional record in the VEDA table where the POSNR value matches the POSNR value from the VBAP (Item) record.
The link to the VBAP table is straight forward being keyed off of the VBELN (doc number) and the POSNR (item number) fields in both tables.  However, there's isn't a POSNR field in the VBAK (header) table and the VEDA table shows this as a blank value in the POSNR field.
The simplest thing I can think of doing is link the VEDA table to the VBAP and let it retrieve all the exact matches on Sales Doc & Item Number but add two "Additional Fields" to the Query that would represent the Sales Header begin and end dates.
I know how to add an additional field but how would you "re-query" the VEDA table and under which option under the Code tab.
Thanks

Hi Alex
Please see if below example helps you to understand:
Supposing, we are displaying material description within our query.
1. So we define the join with MARA & MAKT while creating infoset in transaction SQ02.
2. We create feild groups to identify the fiels we use for selection and display.
3. Here after selecting language key from MAKT, by default this will take SY-LANGU always for the case.
4. To make it applicable for different languages we can code in INITIALIZATION Event.
5. To do so we can do it by two options: Use menupath: Goto->Code->Initialization
i) First option using variable: <b>MAKT-SPRAS = SY-LANGU.</b>.
ii) Second option using Parameter-Id: <b>SET PARAMETER ID 'SPR' FIELD SY-LANGU</b>.
6. Save & Generate.
Now when we execute the query, we are defaulting the language as System Language.
Hope the above info helps you for better understanding.
Kind Regards
