Updating dynamic itab(deep) - ECC6.0

[Former Member]

Hi, I'm reading a dynamic itab in a loop using type any field symbols. This is working nicely. However I want to alter values in the dynamic internal table. How can I do this? I can extract values from the dynamic itab but cannot seem to write them back. The following is some code to demonstrate.

field-symbols: <fs_alvdata_wa> type any,
                                    <fs_1> type any,
                                    <fs_2> type any.

  loop at <lt_alvdata> ASSIGNING <fs_alvdata_wa>.

    ASSIGN COMPONENT 'SOMEFIELD' OF STRUCTURE <fs_alvdata_wa> to <fs_1>.

     if <fs_1> = '1'.   
      <fs_1> = '2'.
     endif.   

*This part is missing.  How do I update <fs_alvdata_wa>-'SOMEFIELD' with <fs_1>???

*This part is missing.  How do I update <fs_alvdata_wa>-'SOMEFIELD' with <fs_1>???

    modify <lt_alvdata> FROM <fs_alvdata_wa>.

  endloop./

Thanks in advance,

Kevin,

As you are working with field symbols you do not have to use MODIFY at all. When you modify the value of <fs_1> you are already modifying the internal table.

Hi Arseni, thanks much for your response. When I do this, change the value of <fs_1>, it is not changing the value in the internal table. Am I missing something?

Ooops, I saw my problem. It was during my debug session, you are right it was changing the value in the internal table, like an idiot I was looking at another variable.

Thanks much,

Kevin

Hello Kevin

You can try code below as a sample:

FIELD-SYMBOLS: <lt_alvdata> TYPE ANY TABLE,
               <fs_alvdata_wa> type any,
               <fs_1> type any,
               <fs_2> type any.

 DATA:
    BEGIN OF t_month OCCURS 0,
      month(10) TYPE c,
    END OF t_month.

ASSIGN t_month[] TO <lt_alvdata>.

t_month-month = 'January'. APPEND t_month.
t_month-month = 'February'. APPEND t_month.
t_month-month = 'March'. APPEND t_month.



  loop at <lt_alvdata> ASSIGNING <fs_alvdata_wa>.

    ASSIGN COMPONENT 'MONTH' OF STRUCTURE <fs_alvdata_wa> to <fs_1>.

    IF sy-subrc EQ 0.
      <fs_1> = '123'.
    ENDIF.

  endloop.

Hi

U can pass the below 2 values into some varible otherwise u can takb one temprary variable and pass the '2' value into

that varible.

if <fs_1> = '1'.

<fs_1> = '2'. "or VAR1 = <FS_1>

<fs_alvdata_wa>-'SOMEFIELD' = <fs_1>. "OR = VAR1

modify <lt_alvdata> FROM <fs_alvdata_wa> INDEX SY-TABIX.

endif.

We can use append statement. No need to use the modify statement.
