Select join

[former_member687484]

The data selected for a given vendor is compared to the data selected for the other vendors.

The following fields are compared:

Name: LFA1- NAME1

Address ID: LFA1 – ADRNR

Street: LFA1 – STRAS

City: LFA1 - ORT01

VAT reg number: LFA1 – STCEG

Phone number: ADR2 - TEL_NUMBER

Bank account: LFBK – BANKN

If any field matches to another vendor in the selected data, the vendor is added to the output dataset.

how can i, select and join the Records when they are Same, From Table (lfba1, lfb1,adr2 and lfbk) to a new table? in ABAP

Hello adib.1213

Something like the below code. Not 100% sure if it will work, wrote it in the forum's editor. Also, not sure about the performance.

SELECT lfa1~lifnr
  FROM lfa1
  JOIN adr2
    ON adr2~addrnumber = lfa1~adrnr
  JOIN lfbk
    ON lfbk~lifnr = lfa1~lifnr
  LEFT OUTER JOIN lfa1 AS lfa1_copy
    ON ( lfa1_copy~name1 = lfa1~name1 OR lfa1_copy~adrnr = lfa1~adrnr OR /and other fields from LFA1/ )
    AND lfa1_copy~lifnr <> lfa1~lifnr
  LEFT OUTER JOIN adr2 AS adr2_copy
    ON adr2_copy~tel_number = adr2~tel_number
    AND adr2_copy~addrnumber <> adr2~adrnr
  LEFT OUTER JOIN lfbk AS lfbk_copy
    ON lfbk_copy~bankn = lfbk~bankn
    AND lfbk_copy~lifnr <> lfbk~lifnr.
  WHERE lfa1_copy~lifnr IS NOT NULL 
     OR adr2_copy~adrnr IS NOT NULL
     OR lfbk_copy~lifnr IS NOT NULL.

But this query, even if it works (which I'm not 100% sure), has one significant issue - only vendors which have records in all tables (LFA1, ADR2, LFBK) are compared.

If you'd like to compare these tables separately, then you'd probably need to write separate queries.

Kind regards,

Mateusz

thanks for Replaying me,

for first steps, for the first part of my task i write this code and its work.

**TABLES : LFA1, LFB1, LFBK, ADR2.

SELECTION-SCREEN BEGIN OF BLOCK B1 with frame title text-001.

select-OPTIONS : S_kTOKK for LFA1-KTOKK,
S_BUKRS for LFB1-BUKRS.

SELECTION-SCREEN end of BLOCK B1.

*SELECT LFA1~*

Select
LFA1~LIFNR,
LFA1~NAME1,
LFB1~BUKRS,
LFA1~ADRNR,

LEFT JOIN ADR2 on LFA1~ADRNR eq ADR2~ADDRNUMBER
WHERE LFA1~KTOKK in @S_KTOKK and LFB1~BUKRS in @S_BUKRS
INTO TABLE @data(Lt_Vendors).**

for the second step to select and join the fields with same values from this 4 table i need to a new selection.?

logically i need an output table (X), that Select and join are those/this fields from this tables ( FLA1,FLB1,ADR2 and LFBK) that they have a same values in this fields Like

Hello adib.1213

Yes, if I understand your requirement correctly, and looking at what you've already written, you'd need at least one more SELECT query to get the vendors with the same data. However, most of these fields that you want to check don't look like fields that are indexed. This means that a DB query based on these fields (with OR condition for some of these tables) might be quite slow (depends on the DB engine you have, might be a different story if you run on HANA).

If you select only those fields you listed, then I wonder if it's not a better idea to load all the records into internal table(s) and compare the fields' values in memory.

Kind regards,

Mateusz

It depends of your needs.

1)

You can also create simple SQL select for one field. i.e Name.

And next use UNION to select vendors for another field i.e Street.

and so on.

UNION returns only unique rows. So no duplicates at the end.

2)

EXISTS might be also an option in some scenarios.
