Problem with JOIN, repat data

[Former Member]

Hello,

I have query below:

SELECT a~j_3gblart "Clase documento
          b~j_3gbelnri  "Número de documento PBE
          b~j_3gposnri " Número de posición PBE
          b~j_3guposnr "Subposición
          b~erdat      "Creado el:
          b~ernam      "Creado por
          b~pernr      "Nº personal
          b~j_3gemppsp "Elemento PEP
          b~j_3gemppro "Nº proyecto
          b~j_3gempkos  "Cemtro de coste
          b~j_3gbelsta  "Stat.doc.interno
          b~j_3gbelste  "Stat.doc.externo
          b~j_3gempfae  "Destinatario
          b~j_3glvart     "Clase Actividad
          b~matnr       "Material
          b~j_3gdatlab  "Fe.prest.actividad
          b~j_3gmenge   "Cantidad
          b~j_3gmeins   "Unidad de medida
          c~name1
          c~name2
          d~eqart  " Categoria del Equipo
          d~vbeln  " Documento Venta
          d~posnr  "Posicion
          d~netwr  "Valor Neto
          d~waerk  "Moneda
          e~vbeln AS vbeln2 "vbeln de la VBRP
       FROM j_3gbelk AS a

     INNER JOIN j_3gbelp AS b
     ON a~mandt EQ b~mandt
     AND a~j_3gbelnri  EQ b~j_3gbelnri
     INNER JOIN vbap AS d ON d~j_3gbelnri EQ b~j_3gbelnri
     LEFT JOIN vbrp AS e ON d~vbeln EQ e~aubel
     INNER JOIN kna1 AS c ON c~kunnr = b~j_3gempfae
     INTO CORRESPONDING FIELDS OF TABLE it_alv
     WHERE b~j_3gbelnri IN p_etm
     AND   b~j_3guposnr IS NOT NULL
     AND   j_3gdatlab IN p_factiv
     AND   j_3gblart IN p_cdoc
     AND   b~equnr IN p_equipo
     AND   b~pernr IN p_person
     AND   b~j_3gempfae IN p_desti
     AND   eqart IN p_catequ.

When I run my ALV report with this document: J_3GBELNRI =  2000003987 and I get repeat data:

If I go to the table, I get only 12 rows, this is the correct result, and I want to have this result in my ALV Report, Could anyone can help me?

Hi,

please remove VBRP (e) from the JOIN and check the result. VBRP might give several matches, where one will be fine.

Hello,

I have removed the VBRP, and now print less data, but, Its continues much data,I have three records for eachone

HI.

INNER Join means 1 on 1 .. Left Join mean 1 on every null value (no references) it matches. Well you should study better a limit range of data and corrispondences between tables.

That's a standard behaviour for a sql operation

Hope to help

Bye.

Hi Luis,

I think is not a good practice this query join. I recommend you have no more than 2 tables in join, and you can use others query by separately.

In your loop you will need READ for your other transparents tables.

I hope help my advice.

Hello gurus, now I have identify the problem, in my first table (J_3GBELP) I have 12 rows if with this key: J_3GBELNRI = 2000003987, in VBAP I have 3 rows with this key, "but"  in VBAP exist VBELN, this value, is not equal, then, this value repeat my query,  12 * 3 = 36 rows. Please see image below:

Anyone can help me?

Hi.

You could use advanced SQL command selection, as nested select in the where clause but this gives a low performance selection.

IF I understood your needs you want to know only if your J_3GBELNRI exist in VBAP but you don't want to get occurrences repeated.

Instead I suggest to reduce data you need, using a few internal tables with data filtered and match them, because till you'll use standard table you'll have to face primary key rules.

Hope to help

Hi,

did you try to add a DISTINCT after SELECT ?
