Modify Internal Table using a criteria

[former_member998274]

Hi, sorry if this question is too basic because I just started with ABAP and not familiar with the way it operates.

Objective :

Put the data fields from it_table into it_files with different field name.

it_files contains key1, field1, field2, field3, field4, field5 --> data retrieved from data file

it_table contains key1a, field1, field2a, field3a --> data retrieved from table

it_files and it_table can be linked using key1 and key1a.

Using the standard modify function it doesn't allow me to match key1 to key1a.

In this situation, normally how you do it in ABAP ?

If it allow me to match key by key and then column to column, it will be much easier, however it is not something I can figure out.

Thanks for any assistance.

Hi David,

Are you transporting only FIELD1? if yes, you can do it like this:

Loop at t_tab1 into w_tab1.

read table t_tab2 into w_tab2 with key key1a = w_tab1-key1.

v_tabix = sy-tabix.

modify t_tab2 index v_tabix from w_tab1 transporting field1.

Endloop.

Fieldnames should be the same if you want to modify the table data.

Hope this helps.

Sorry, I am not clear in my question.

it_files --> data retrieved from data file into this internal table

key1

field1

field2

field3

field4

field5

it_table --> data retrieved from table

key1a

field1

field2a

field3a

I need to update field1, field2a, field3a from it_table to it_files matching key1 and key1a.

Final, all data must be in it_files.

Take note, the field name in both internal table may not be the same.

Hi david,

If the fields,

field1, filed2a, filed3a are of the same type as that of it_table, then you can use move-corresponding and modify it. Else you can try the following,

loop at it_table.

read table it_files with key key1 = it_tables-key1a.

if sy-subrc = 0.

it_files-field1 = it_tables-field1.

it_files-field2a = it_tables-field2.

it_files-field3a = it_tables-field3.

modify it_files.

clear: it_files-field1, it_files-field2a, it_files-field3a.

modify it_files.

eendif.

endloop.

Hi,

Check this.

loop at it_files into wa_files.
  read table it_table into wa_table with key key1a eq wa_files-key1.
  if sy-subrc eq 0.
    wa_files-field1 = wa_table-field1.
    wa_files-field2 = wa_table-field2a.
    wa_files-field3 = wa_table-field3a.
    modify it_files from wa_files.
 endif.
endloop.

Thank you all for your assistance.

I will try it out and provide credit accordingly. Appreciate your expertise.

Hi David,

you can try the following code

loop at it_table.

read table it_files with key key1 = it_tables-key1a.

if sy-subrc = 0.

move-corresponding it_table to it_files.

modify it_files.

eendif.

endloop.

hi

the following code will make your doubts clear.

loop at it_files into wa_files.
read table it_table  into wa_table with key1a eq wa_files-key1.
if sy-subrc eq 0.
wa_files-field3 = wa_table-field3.
modify it_files from wa_files.
endif.
endloop.

Hi David,

Try the below code,

field-symbols : <FS_table > type X_table.

data: it_table type standard table of x_table.

loop at it_files into w_files .

read table it_table ASSIGNING <FS_table > with key key1a = w_files-key1.

if sy-subrc = 0.

<FS_table > -key2a = 'XYZ' -

---

> Here your key2a value will be changed directly in the table

endif.

endloop.

otherwise try the below code.

loop at it_files into w_files .

read table it_table ASSIGNING w_table with key key1a = key1.

if sy-subrc = 0.

w_table-key2a = 'XYZ'.

w_table-key3a = 'ABC''.

modify it_table from w_table transporting key2a

key3a

where key1a = w_files-key1.

endif.

endloop.

but the first solution will give you a better performance.
