Implement a UNION clause

[Former Member]

Hi All,

My requirement is simple.

I want a Z table which combines the distinct Cost Center and Employee Pernr combination from two tables into one ztable.

e.g.

table 1..................................

Cost Center Pernr

A emp1

A emp2

A emp3

B emp1

C emp3

table 2.................................

Cost Center Pernr

A emp3

B emp1

B emp2

B emp3

Resultant ZTable.................

Cost Center Pernr

A emp1

A emp2

A emp3

B emp1

B emp2

B emp3

C emp3

In SQL a simple UNION clause will do the trick, but in ABAP i am not able to achieve it.

Please advise.

insert ztable from table table1.

insert ztable from table table2.

or

collect both the 2 table values in on iternal table and insert it.

insert ztable from table table3.

Make n SQL statements, the first with inserting into tables, the other with appending. See onloiune help on howto select vakues into internal tables.

Hi Saqi....

types : begin of ty_tab,

cc type string,

emp type string,

end of ty_tab.

data : it_tab1 type table of ty_tab.

data : it_tab2 type table of ty_tab.

data : it_result type table of ty_tab.

data : wa_tab type ty_tab.

clear wa_tab.

wa_tab-cc = 'A'.

wa_tab-emp = 'emp1'.

append wa_tab to it_tab1.

clear wa_tab.

wa_tab-cc = 'A'.

wa_tab-emp = 'emp2'.

append wa_tab to it_tab1.

clear wa_tab.

wa_tab-cc = 'A'.

wa_tab-emp = 'emp3'.

append wa_tab to it_tab1.

clear wa_tab.

wa_tab-cc = 'B'.

wa_tab-emp = 'emp1'.

append wa_tab to it_tab1.

clear wa_tab.

wa_tab-cc = 'C'.

wa_tab-emp = 'emp3'.

append wa_tab to it_tab1.

***********

clear wa_tab.

wa_tab-cc = 'A'.

wa_tab-emp = 'emp3'.

append wa_tab to it_tab2.

clear wa_tab.

wa_tab-cc = 'B'.

wa_tab-emp = 'emp1'.

append wa_tab to it_tab2.

clear wa_tab.

wa_tab-cc = 'B'.

wa_tab-emp = 'emp2'.

append wa_tab to it_tab2.

clear wa_tab.

wa_tab-cc = 'B'.

wa_tab-emp = 'emp3'.

append wa_tab to it_tab2.

clear wa_tab.

loop at it_tab1 into wa_tab.

append wa_tab to it_result.

clear wa_tab.

endloop.

clear wa_tab.

loop at it_tab2 into wa_tab.

append wa_tab to it_result.

clear wa_tab.

endloop.

sort it_result by cc emp.

delete adjacent duplicates from it_result comparing cc emp.

clear wa_tab.

loop at it_result into wa_tab.

write : wa_tab-cc.

write : wa_tab-emp.

clear wa_tab.

endloop.

Hope this above code helps you...

It is able to create a union of the two tables...

Please revert back in case of any issues...

you can take the values of the it_result into your resultant ztable like...

ztable [] = it_result [] .

[Maciej_DomagaBa]

refresh table_3.
append lines of table_1 to table_3.
append lines of table_2 to table_3.
sort table_3 by CostCenter Pernr.
delete adjacent duplicates from table_3 comparing CostCenter Pernr.
