Abap query table link

Question

Experts Im doing an abap query then I just link the tables adr2 , adr3 , adr6 and lfa1 and lfb1 in infosets "join button"..then show the fields that I need in sq01.But I was wondering why my data becomes times 4..it repeatedly display my data in FOUR times..
What do you think is the cause of that?

Answer 1

dear,
it depends on which table you selected first (Table join using basis table) and how do you insert next tables.
i am talking about the info-set creation step.
let's do a simple query.
run SQ02. type new infoset name and hit Create.
type name and type MARA for "Table join using basis table" radio button. Hit Continue.
now insert (add) tables: MARC, MCHA, CABN, CAWN
think about Inner Join or Left Outer Join !!'
say, if you need to display all materials (even if not exist on plant) set Left Outer Join. if you're after materials existing on plant keep default Inner Join.
friend, my example above is only the example.
make sure you undertsand how to build a sap query in general.
never set many tables at once. insert 2-3 tables, return to your query (SQ01) or create it, adjust it and test. step by step - table by table. add the new table in infoset, add the fields, generate it and come back to your query. adjust it and test.
good luck!
