Better option i feel is join bseg and bkpf. Get data to internal table. For this records get data from SKAT & LFA1. This will have better performance than joining all 4 tables. Let me know if you need exact join fields and related psudocode.

Award points, if you find this solution helpful.

hi,

if u want to join more than 3 tables than go for views or use FOR ALL ENTRIES than joins as joins degrades performance of the program for more tables.

i think for ur purpose just create a database view and use in ur program.

if helpful reward some points.

Hi Hemal,

You can use join statement to join at max four tables.

For your requirement you can do that.

Refer this pseudo code :

SELECT A~<Field Name>

A~<Field Name>

B~<Field Name>

B~<Field Name>

C~<Field Name>

C~<Field Name>

D~<Field Name>

D~<Field Name>

INTO CORRESPONDING FIELDS OF TABLE I_TAB

FROM BKPF AS A INNER JOIN

BSEG AS B ON A_{<Key Field> = B}<Key Field>

SKAT AS C ON A_{<Key Field> = C}<Key Field>

LFA1 AS D ON A_{<Key Field> = D}<Key Field>

WHERE <Condition>.

Refer this two table joining code for joining four tables.

SELECT A~VBELN

A~FKDAT

A~KUNAG

A~KUNRG

B~NAME1

B~ORT01 INTO CORRESPONDING FIELDS OF TABLE I_INVOICE

FROM VBRK AS A INNER JOIN

KNA1 AS B ON

A_{KUNAG = B}KUNNR

WHERE A~VBELN IN P_VBELN.

Reward points if helpful.

Hi,

<b>First make not that you can not Join the table which is Cluster table.</b> BSEG is one of that kind of table and you can not join these

I would suggest Select from BKPF and then go to BSEG and use <b>For all entries </b>

and then go to SKAT ans use <b>For all Entries</b> and same way for LFA1

Thanks,

JOin on 4 different tables is not recommended and BSEG is a cluster.

Try creating Views and use it or just go for select queries individually.

hi,

we can join those 4 tables , but in the performance level it is not recommended. But i am forwarding the sample code for that , go through it.

select a~bukrs

a~belnr

b~gjahr

b~buzei

c~lifnr

c~land1

d~saknr

d~mcod1

from bkpf as inner join bseg as b

on a_{bukrs = b}bukrs

inner join lfa1 as c

on b_{lifnr = c}lifnr

inner join skat as d

on c_{mcod1 = d}mcod1.

Hi,

BESG is clustertable and JOINS doesnt work on Cluster tables.
