Dynamic internal table

Former Member — Wed, 07 May 2008 08:38:22 GMT

Hi,

I have date range in selection options. I have to display the dates in the columns of ALV what will dynamically generate. In my internal table i Have 2 column and then date that will be dynamic. After that i will calculate and show the values under that dates.

DES VAL 02.05.2008 03.05.2008 04.05.2008

S10 COD 40.6700 40.5700 40.7000

S28 15m 40.7130 40.6315 40.7367

S35 30s 40.7570 40.6863 40.7767

S49 45b 40.7870 40.7288 40.8067

S52 60y 40.8166 40.7690 40.8405

S55 75r 40.8408 40.8029 40.8719

S8 90e 40.8650 40.8386 40.9002

Please dont send link or example. Pl be specific to my requirement, how to define that type of internal table,assigning value to it and display.

Thanks

Kannaiah Kavuri

Thanks for your reply..

can u explain it more. I have 2 field fixed in my internal table and rest dates are dynamic.

how to declear it?

DATA: BEGIN OF itab OCCURS 0.
              DES(4) type c,
              VAL(3) type c,

???????????????????????????
          DATA: END OF itab.

And how to declear FIELD-SYMBOL according to my internal table?

FIELD-SYMBOLS : <f_fs> TYPE table,
                            <f_fs1> TYPE table,
                             <f_fs2> TYPE ANY,
                             <f_fs3> TYPE ANY,
                              <f_fs4> type any,
                              <f_field> TYPE ANY.

Hi,

1. Declare the internal table with two fields only.

2. Take the select options data into a range table.

3. Create a field catalog by taking the two fields from the internal table.

4. Also append the data in ranges to the field catalog.

5. call the method with exporting parameter field catalog and import the internal table d_ref.

6. Assign it to <f_fs>.

Now you can use the table <f_fs>.

DATA: d_ref TYPE REF TO data,
           i_alv_cat TYPE TABLE OF lvc_s_fcat, " To build the field catalog 
           ls_alv_cat LIKE LINE OF i_alv_cat.

              DES(4) type c,

* Take the range for your select option
Data:  r_date type range of s_date,
            wa_date like line of r_date.

how to declear

 2. Take the select options data into a range table.

what u have wrote is giving syntax error.

              WA_DATE LIKE LINE OF R_DATE.

Thanks a lot.

So <f_fs>. is my internal table. So now i have to fill the internal table. So now i have to put data in that internal table. So where anh how to use SELECT statement for that <f_fs> internal table.

suppose my select statement is like this...

select DES
                  VAL
                  TCURR  <dynamic field values>
       from TCURR
      into corresponding fields of itab
     where date in s_date.

Thanks a lot,

But now the problem is if im giving a range of date

02052008 to 05052008

its giving error

The type "" has no structure and therefore no comp 6 -20080502

So what to do now?

Re: Dynamic internal table

Hi,

You need to get the data into dynamic internal table and populate output by using write. then you wont get the error.

Hallo,

i'm beginner at ABAP and i try to create a dynamic table. I found your answer here and it helped me to get as far as calling method cl_alv_table_create=>create_dynamic_table but i get an error. Can you help me here? What You mean by populating the internal table?!

Thanks a lot in advance& best greetings!

Hi again!

I just found the answer. I didn't supply values for ref_field and ref_table.

Now it works!

Thanks a lot!
