Hi Sri Lalitha,

I believe you can use the below mentioned code to fulfill your need

data strng1 type string value 'aaa, bbbb, cc, dddddd, bbb,cccccc,dd,eee'.

data strng2 type string.

data strng3 type string.

data : begin of fs,

col1(20) type c,

col2(20) type c,

col3(20) type c,

col4(20) type c,

end of fs.

data itab like table of fs.

string2 = string.

while string2 <> space.

split string2 at ',' into fs-col1 fs-col2 fs-col3 fs-col4 string2.

append fs to itab.

clear fs.

endwhile.

loop at itab into fs.

write / fs.

endloop.

Let me know in case you require any further inputs.

BR/Thanks

Hi,

You can use the SPLIT statement for your requirement. Check for SPLIT statement , use different variable to get the value .

Hi Sri Latha,

Below is the answer to your further query.

Suppose screen parameter is string2.

Then you enter string2 = aaa, bbb.

split string2 at ', ' into stg1 stg2.

The corresponding values in string2 variable will go in stg1 and stg2 i.e.

stg1 = aaa and stg2 =bbb.

Please validate the same at your end as well.

Hi SriLatha,

As all the above suggested, you can use the SPLIT statement. But there an issue will arise. How many TO fields needs to be declared and how many of them needs to be used in the SPLIT statements. Means, these can be dynamic.

So I will suggest you can go with the following logic for SPLIT statement.

DATA : gt_str TYPE TABLE OF tdline.

SPLIT IP_TEXT AT ',' INTO TABLE gt_str.

So this will split all the values into a table and this will be dynamic.

Hi,

If your requirement is to read the screen field value of any standard screen and to pass the values to separate variables, follow the below code.

Declare a field symbol of type field required to be read.
Use assign statement to read the value of field.

For example:

"Field Symbols
FIELD-SYMBOLS: <fs_vbak> TYPE vbak.

        "Read the VBAK structure populated for SO
        ASSIGN ('(SAPMV45A)VBAK') TO <fs_vbak>.
        IF <fs_vbak> IS ASSIGNED.

"Put logic required

ENDIF.
