Doubt in Inner Join.

[Former Member]

Hi all,

In a report program i have used a inner join. I am getting error in the where condition. Here I have furnished part of my code for ur reference.

Tables : mara, makt, mard.

data : begin of itab occurs 0,

matnr like mara-matnr,

maktx like makt-maktx,

lgort like mard-lgort,

labst like mard-labst,

end of itab.

parameters : matnr like mara-matnr.

start-of-selection.

select mara_{matnr makt}maktx mard_{lgort mard}labst into corresponding fields of iab from mara inner join maktx on mara_{matnr = makt}matnr inner join mard on makt_{matnr = mard}matnr where matnr eq matnr.

• in the where condition I am getting the following error message.

matnr has two meanings in data dictionary.

Please help me in sort out this problem and also tell me more abt inner joins.

thanks.

HI,

You can achieve this in two ways:

1st:

into corresponding fields of TABLE itab

2nd:

if you have inner join you don't need where any more at all! you already have connections.

if you still need then use:

tablename~fieldname

for both sides!

if in your example matnr from left side is local or global variable then you have problem with some naming conventions which usually are used in SAP.

try 1st points at the beggining

i'd write your select in this style

Code:

select mara~matnr

makt~maktx

mard_{lgort mard}labst

into corresponding fields of table itab

from ( mara

inner join makt on makt_{matnr = mara}matnr

and makt~spras = sy-langu )

inner join mard on mard_{matnr = mara}matnr.

OR

Code:

select mara~matnr

makt~maktx

mard_{lgort mard}labst

into corresponding fields of table itab

from ( mara

inner join makt on makt_{matnr = mara}matnr )

inner join mard on mard_{matnr = mara}matnr

where

makt~spras = sy-langu.

Like this:

TABLES : mara, makt, mard.

DATA: BEGIN OF itab OCCURS 0,
        matnr LIKE mara-matnr,
        maktx LIKE makt-maktx,
        lgort LIKE mard-lgort,
        labst LIKE mard-labst,
      END OF itab.

PARAMETERS : matnr LIKE mara-matnr.

START-OF-SELECTION.

  SELECT mara~matnr makt~maktx mard~lgort mard~labst
    INTO CORRESPONDING FIELDS OF itab
    FROM mara
    INNER JOIN maktx
      ON mara~matnr = makt~matnr
    INNER JOIN mard
      ON makt~matnr = mard~matnr
    WHERE mara~matnr EQ matnr.              "<====

hi frd,

ur code is following

"

Tables : mara, makt, mard.

data : begin of itab occurs 0,

matnr like mara-matnr,

maktx like makt-maktx,

lgort like mard-lgort,

labst like mard-labst,

end of itab.

parameters : matnr like mara-matnr.

start-of-selection.

select mara_{matnr makt}maktx mard_{lgort mard}labst into corresponding fields of iab from mara inner join maktx on mara_{matnr = makt}matnr inner join mard on makt_{matnr = mard}matnr where matnr eq matnr. "

since u used the alias name mard for both components lgort and labst, system confused to consider alias names, u change the alias names ,a nd try it one again for the corresponding where condition.

and once again check ur itab instead of iab in select statement.

Hi,

Use SPRAS(Language key) in your where condition.
