Can I di Inner Join on 2 tables by using only 1 key field?

Hello,
I hv 2 Std. SAP tables, KNVV, KNKK.
- KNVV - does hv 2 key fields (KUNNR and some other, say X)
- KNKK - does hv 2 key fields (KUNNR and some other,say Y)
I want to build a inner join on these 2 tables.
So, Can I do a INNER JOIN on these 2 tables by using ONLY one key field (its KUNNR)? bcoz, there is ONLY common field!!
thank you

Hi,
The correctness depends on your bussiness requirement. If the common key field is not a primary key, you may end up fetching duplicate entries which you may have to delete after the select query. You dont have to take of any extra precautions in a inner join select query compared to a ordinary select query. Just make sure you use most of the primary key fields of both the tables in the where clause of the select query for better performance

Inner join on Buffred table and not buffered table.

Hi guys,
   Can you suggest me how can i write select query using inner join on buffered table and not buffered table. i written like this. is it right?
SELECT a~vbeln
         a~vkorg
         a~kunnr
         a~kunag
         a~wadat_ist
         a~xblnr
         b~bukrs
   FROM likp AS a INNER JOIN tvko AS b
    ON avkorg = bvkorg BYPASSING BUFFER
INTO TABLE itab_likp
WHERE vbeln = s_vbeln.
Thanks.

Hi Raj ,
Please find below my Commentes :
1. When you use "Bypassing buffer" clause in Select statement , the data what is there in the buffer of application sever is always ignored and Read is performed from the Physical database always. This Clause is advisable where you require realtime data (Not recommended generally in reporting)
2. It is advisable that you should not use small table in the innerjoin with big table. In the query you have written there are 2 tables:- LIKP and TVKO outof which TVKO is a master table containing very few records than LIKP (Contains huge data for Delivery header).
So my recommendation will be : -
1. Eliminate the "Bypassing Buffer" clause from your Query
2. Break the select query into 2 select queries breaking the join and with some ABAP logic populate the Internal table "itab_likp".
This will be optimum way inwhich you can write the select query for your senarion. Also Ensure that indexes are being used for better selectivity.
Hope this will help to you.

How can I see in what maps some table is used?

Hi,
Anyone can tell me how can I see in what maps some table is used, without open all of then?
Thanks,

Good morning Gustavo,
OWB has some public views defined which can provide you with this information. Check Appendix D (Warehouse Builder Public Views) of the OWB User Guide for all info.
Log in as the owner of the design time repository, if you run the following query you'll have a basic overview of whic table is used in which mapping:SELECT MAP_NAME         MAPPING_NAME

Access table cells using tab key with iterators

Hi,
I use a tableview with iterator and allow users to mouseclick certain column cells. I capture these user interactions using server event "onCellClick". But I cannot access these cells using tab key instead of mouse click. But tab key is a must for visibly challenged users. Is there any way to access table cells using tab keys (with iterators)?
I use icons in those cells to replace check box and change the icons to differentiate checked/unchecked status.

Hi Craig,
Thanks for your effort.
But I was able to solve my problem. I don't think I gave all the information to simulate my problem in your environment. I used images in certain table cells and was not able to access those cells using tab key or access key. Tag <img> doesn't have the attributes tabindex and access key.
I solved the problem by surrounding the <img> by anchor tag <A>, which has both attributes. I did these changes within the iterator method RENDER_CELL_START using CL_BSP_BEE_TABLE.
In the event handling, I had to do separate processing for mouse click event and key press event for those cells.
For visibly challenged users:
They can access those cells by tab key or access key and the key press event is used to capture when they hit enter key.
So this problem is irrelevant to service packages (SP38,..).

Only key fields of table-cluster in where-condition for better performance?

Hi,
Say my cluster table is having following key fields: KEY1, KEY2, KEY3, KEY4.
And, my table-cluster is having following key fields: KEY1, KEY2, PAGENO .. [PAGENO is always there in a table-cluster].
Now, I have two versions of my (Open SQL) SELECT-WHERE clause:
a) SELECT *
 WHERE KEY1 EQ LV_KEY1
 AND KEY2 EQ LV_KEY2
 AND KEY3 EQ LV_KEY3.
b) SELECT *
 WHERE KEY1 EQ LV_KEY1
 AND KEY2 EQ LV_KEY2.
Please guide me whether version (a) or version (b) will be executed faster? In case of version (b), I will have to filter data using ABAP code corresponding to KEY3.
Regards,
Kamlesh Dhera H. R.

I think most experienced ABAPrs would tell you to try both, compare runtimes, and use the one that's more efficient. SAP provides "get run time field <fieldname of type i>. Get run time at start, get run time at end, and subtract start from end to get the time in microseconds (1 second / 1,000,000 ).
Run several times to minimize effect of buffering and system load activity, and you'll see which method produces lower run time.

Inner join on four tables

hi all,
i am facing the problem with the inner join in the select query for 4 tables.
can i use the inner join for tables in SAP 6.0 version,
it is going to dump.

hi this is the dump ,
In a SELECT access, the read file could not be placed in the target
field provided.
Either the conversion is not supported for the type of the target field,
the target field is too small to include the value, or the data does not
have the format required for the target field.

Confusion in Select query having a inner join on single table

Hi,
I was going through coding and came a accross a select query which has a inner join on a single table. I am getting confused while analysing this . Please someone can help me analysing this query.
select

         and s~MATERIAL IN ( Select mat_sales
            from Table2 group by mat_sales ).
Thank you
Kusuma

I don't see any use of the INNER JOIN here.
But what's the meaning of the last selection clause?
s~MATERIAL IN ( Select mat_sales
            from Table2 group by mat_sales ).
Is that native SQL or something?

Inner join on internal table

HI all,
How to access data from two internal table using join condition ?
suppose i have tow internal table itab and jtab and i want to access data by using inner join on this tow table.
please tell .
thanx..

hi,
You can use PROVIDE ENDPROVIDE statements in ABAP to achive this.
Check the below documenttaion.
PROVIDE
Syntax
PROVIDE FIELDS {*|{comp1 comp2 ...}}
               FROM itab1 INTO wa1 VALID flag1
               BOUNDS intliml1 AND intlimu1
               [WHERE log_exp1]
        FIELDS {*|{comp1 comp2 ...}}
               FROM itab2 INTO wa2 VALID flag2
               BOUNDS intliml2 AND intlimu2
               [WHERE log_exp2]
        BETWEEN extliml AND extlimu
        [INCLUDING GAPS].
ENDPROVIDE.
Effect
The statements PROVIDE and ENDPROVIDE define a loop through a statement block. In this loop, any number of internal tables itab1 itab2 ... are processed together. A single table can appear several times. For every table itab you must specify a FIELDS clause. After FIELDS you must specify the character * for all components or a list comp1 comp2 ... for specific components of the relevant table. The names of the components comp1 comp2 ... can only be specified directly.
To be able to process internal tables using PROVIDE, all tables itab1 itab2 ... must be fully typed index tables and contain two special columns that have the same data type (d, i, n, or t) for all relevant tables. For every table you must specify the names intliml1 intliml2 ... and intlimu1 intlimu2 ... of these columns using the addition BOUNDS.
The columns intliml1 intliml2 ... and intlimu1 intlimu2 ... in every row of the relevant internal tables must contain values that can be interpreted as limits of closed intervals. Within a table, the intervals specified in these columns must not overlap and must be sorted in ascending order. The intervals therefore make up a unique key for every row.
For every table you must specify a work area wa1 wa2 ... compatible with the row type and a variable flag1 flag2 ..., for which a character-type data type with length 1 is expected. In the PROVIDE loop, the components specified after FIELDS are filled with values in the relevant work areas wa1 wa2 ... for every specified internal table. The variables flag1 flag2 ... are also filled. A work area wa1 wa2 ... or a variable flag1 flag2 ... cannot be specified more than once.
With the BETWEEN addition you must specify an interval extliml, extlimu. It must be possible to convert the data objects extliml and extlimu into the data types of the respective columns intliml1 intliml2 ... and intlimu1 intlimu2 ... of the individual tables.
The interval limits intliml1 intliml2 ... and intlimu1 intlim2 for every row of all relevant internal tables itab1 itab2 ... that are within the closed interval made up by extliml and extlimu divide the latter into new intervals and every interval limit closes one interval in the original direction. If, within a relevant table, a lower interval limit follows an upper interval limit with no space or gap between them and the components of the corresponding rows specified after FIELDS have the same content, the two intervals are combined and the corresponding interval limits intliml1 intliml2 ... and intlimu1 intlimu2 ... are ignored for the new intervals.
For every interval that is created in such a way and overlaps with at least one of the intervals of a table involved, the PROVIDE loop is passed once. The components of every work area wa1 wa2 ... specified after FIELDS and the variables flag1 flag2 ... are filled with values as follows:
The components intliml1 intliml2 ... and intlimu1 intlimu2 ... of every work area wa1 wa2 ... are filled with the interval limits of the current interval.
If the current interval overlaps with one of the intervals of an involved table, the remaining components of the corresponding work area are assigned the contents of the relevant components of this table row and the variable flag1 flag2 ... is set to the value "X". Otherwise, the work area components and the variables flag1 flag2 ... are set to their Initial value.
Except for intliml1 intliml2 ... and intlimu1 intlimu2 ..., the components not specified after FIELDS are always set to their initial value. The components intliml1 intliml2 ... and intlimu1 intlimu2 ... are always assigned.
The ABAP runtime environment checks for every table involved, whether the condition of sorted and non-overlapping intervals is met within the interval made up by extliml and extlimu and, if necessary, triggers an exception that can be handled.
If the INCLUDING GAPS addition is specified, the system passes the PROVIDE loop for every interval, that is also when the current interval does not overlap with at least one of the intervals of an involved table. In the latter case, the variable flag is of initial value for every relevant table.
You can use the WHERE addition to specify a condition for every table itab1 itab2 ... involved. After WHERE, you can specify any logical expression log_exp1 log_exp2 ... ; the first operand of every comparison must be a component of the internal table. As such, all logical expressions except for IS ASSIGNED, IS REQUESTED, and IS SUPPLIED are possible. You can only specify components that are in the list after FIELDS. Here it is not possible to specify a component using character-type data objects in brackets. The table entries for which the condition is not met are ignored by the PROVIDE loop. You can leave the PROVIDE loop following the instructions in the section Leaving loops.
System fields
The system fields sy-subrc and sy-tabix are set to the value 0 before every loop pass and at ENDPROVIDE. Only if the loop is not passed once, is sy-subrc set to 4 at ENDPROVIDE.
Notes
The relevant internal tables should not be modified in the PROVIDE loop.
The WHERE condition can be used to remove overlaps between the tables involved or to ensure the sorting of the intervals.
In two tables itab1 and itab2, the respective columns col1 and col2 are interval limits of type i. The filling of the internal tables results in the following intervals (rows two and three):
|01|02|03|04|05|06|07|08|09|10|11|12|13|14|
|   Itab1 Int1    |     |Itab1 Int2 |     |
|        |      Itab2 Int1       |        |
| |          ... BETWEEN ...             |
| | i1 |   i2   | i3 |   i4   |i5|     |
The interval specified in the BETWEEN addition to the PROVIDE statement is shown in the fourth row. It serves as a basis for the five intervals in the fifth row represented by i1 to i5. These can be processed in the PROVIDE loop.
Because each of the five intervals overlaps with one of the intervals from rows two and three, the PROVIDE loop is passed five times.
Only the component col3 of wa1 is filled in the first pass, only the component col3 of wa2 in the third pass, and the components col3 of both work areas in the second and fourth passes. The fields valid1 and valid2 are set accordingly.
DATA: BEGIN OF wa1,
        col1 TYPE i,

        col3 TYPE string,

Inner Join of 3 tables is correct or not?

Hi Guys ,
 I have a requirement where i have to join 3 tables i dont know whether the inner Join which i wrote for 3 tables is correct or not.I am not getting any Syntax error but whether the logci below which i wrote gets all the records or not.
The Requirement is
"c. Select the BOL Number entered in the screen and query the table LIKP with the BOL number in the field LIKP-BOLNR. Gather the list of ALL delivery documents (LIKP-VBELN) that is outputted.
d. Query the list of the delivery documents obtained into the table VBFA in the field VBFA- VBELV. From the output that is displayed, select the Follow-On Document Field (VBFA-VBELN) for that item whose Subsequent Document Category (VBFA- VBTYP_N) is R and the Movement Type (VBFA- BWART) is 641. Get the Follow-On document number for each of the above Delivery Document number.
e. Query the table EKBE with the Follow On document obtained above in the field Material Document (EKBE- BELNR). Perform this activity for each of the follow on document obtained above. Get the resultant Purchase Order (EKBE-EBELN) and Item Number (EKBE-EBELP) from the query. After querying will all the Follow-On Documents, get the unique list of PO number and Item Number.
The logic which i wrote is
 Begin of t_PoolSTO_out,
 BOLNR type LIKP-BOLNR,
 EBELN type EKBE-EBELN,
 EBELP type EKBE-EBELP,
 VBELN type LIKP-VBELN,
 VBELNV type VBFA-VBELN,
 End of t_PoolSTO_out.
 Data: i_PoolSTO type Standard table of t_PoolSTO_out.
Select
 a~BOLNR
 c~EBELN
 c~EBELP
 a~VBELN
 b~VBELN
 from LIKP as a
 Inner Join VBFA as b on aVBELN = bVBELV
 Inner Join EKBE as c on bVBELN = cBELNR
 into Table i_PoolSTO
 Where a~BOLNR in S_LBLNE and
 b~VBTYP_N = 'R' and
 b~BWART = '641'.
 My doubt is whether the logic works or not i Mean does i getall the rrecords based on the requirement.?
 If not please tell any alternative logic?
Thanks,
Gopi Anne.

Hi Gopi,
Your code is Good.
But try to avoid Inner join with more number of Tables ...because this is a performance issue..
try to use..
select (primary key fields mainly,other fields) from LIKP into itab where bolnr in p_bolnr(paramater).
next try to use for all entries option..
select (primary key fields mainly,other fields) from VBFA for all entries in itab where (give the condition)....
simillarly do for the other select ....ok this will try to reduce the performance issue....

Problem when doing inner join for three tables....

DATA: V3 TYPE VBAP-MAKTL.
SELECT single vbap~matkl into V3
       from VBAP
       inner join VBFA
       inner join LIPS
          on LIPSPOSNR = VBFAPOSNN
          and vbapvbeln = vbfavbelv
           and vbapposnr = vbfaposnv
             where LIPSVBELN = VBFAVBELN = '0080000834'
             and vbfa~vbtyp_n = 'J'
             and LIPS~J_3ASIZE = '0884'.
Error: Wrong expression "INNER" in from clause...

Hello Tushar,
Why you are using the 3 table inner join. If the volume of data is big then this statement will give to time out. Use "for all entries" statement to select the data from the table.
Like
select field1 field2 from LIPS into i_lips
    where LIPS~J_3ASIZE = '0884'.
select f3 f4 from vbfa into i_vbfa for all entries in i_lips where field1 = i_lips-field1 and so on
and
use same to select data from VBAP.
Hope this will help

How can I extract data from ST03 - what tables are used?

Hi
I currently have to create performance statistics daily for management. To do this I use transaction ST03 and manually copy the previous days Dialog average response time, DB, CPU and GU av. times into a spreadsheet, and also the average dialog response time for 4 key transactions from the transaction profile.
It would be nice to automate this. I was thinking of writing a basic ABAP program to query the relevant tables to extract this data - does anyone know which tables are used? I'd tried running a trace but it was not clear which tables/rows etc would be required.
Thanks
Ross

Ok, that FM is an old one - for NW2004s (700) need to use 'SWNC_COLLECTOR_GET_AGGREGATES'.
Have a basic program below. What I'm trying to do is get the average response time for transactions. I can get 'respti' from the table but I think this is the total response time - what field represents average response time?
Also, the numbers that it's pulling back don't seem to match the numbers in ST03 at all... except 'dcount'. This seems to correct ly show the number of steps... but the other values don't match anything. What am I doing wrong?
Program below...
Cheers
Ross

Find matching records from two tables, useing three key fields, then replace two fields in table1 from table2

I have two tables - table1 and table2 - that have the exact same schema. There are three fields that can be used to compare the data of the two tables, field1, field2, and field3. When there are matching rows in the two tables (table1.field1/2/3 = table2.field1/2/3)
I want to replace table1.field4 with table2.field4 and replace table1.field5 with table2.field5.
I have worked with the query but have come up with goobly goop. I would appreciate any help. Thanks.

If your field1, field2, and field3 combinations in these tables are unique, you
can do a join on them.
Select t1.field4, t2.field4 , t1.field5, t2.field5
from table1 t1 inner join table2 t2 on t1.field1 =t2.field1 and t1.field2=t2.field2 AND t1.field3=t2.field3
--You can update your table1 with following code:
Merge table1 t1
using table2 t2 on
on t1.field1 =t2.field1 and t1.field2=t2.field2 AND t3.field3=t2.field3
When matched then
Update Set
t1.field4= t2.field4
,t1.field5 = t2.field5 ;

Can I di Inner Join on 2 tables by using only 1 key field?
