unable to read table control data in module pool

[Former Member]

Hi Folks,

I am unable to read table control data in module pool.

I can read table control data by using the fm  'dynp_values read' (only if i manually enter values for 'stepl') but how do I populate 'stepl' values?

Thanks and regards,

In the POV, use FM DYNP_GET_STEPL.

I am trying to read the values on a user input (In PAI).

Thanks,

[RaymondGiuseppi]

So add some FIELDS statements in PAI before you need the data ?

Can you explain your scenario ?

HI Raymond,

Thanks for your reply.

On pressing save I am  trying to fetch the data from the table control of the screen.

By Looping over the internal table attached to the table control I am not able to fetch the data.

Nor I am able to use dynp_values_read as I am not able able to populate 'stepl' field value.

I suppose that POV can be called only after the PAI block.

By Looping over the internal table attached to the table control I am not able to fetch the data.

That must be done in PAI not in a called form.

Did you put a LOOP AT itab. with a CHAIN/ENDCHAIN and every required FIELD, followed by a MODULE checker ON [CHAIN-]REQUEST to validate data and a MODULE update to modify the internal table, and ise you USER-COMMAND executed after the loop (exception for a  previous call with the AT EXIT-COMMAND option ?

PROCESS AFTER INPUT.
  MODULE user_command AT EXIT-COMMAND.
  CHAIN.
    FIELD field1.
    FIELD field2.
    MODULE check_header_field?
  ENDCHAIN.
  LOOP AT itab.
    MODULE load_current_itab_into_memory.
    CHAIN.
      FIELD itab-field3.
      FIELD itab-field4.
      FIELD itab-field5.
      MODULE check_and_update_itab_values ON CHAIN-REQUEST. " PAI ne PBO values
    ENDCHAIN.
  ENDLOOP.
  MODULE user_command.

NB: (my 2 cents' worth) DYNP_VALUES_READ as DYNP_GET_STEPL are intended to be used in at POV to manage F4, they can be used elsewhere but without warranty of success, and I doubt you can use those to  read multiple lines of a table control, the get stepl only convert the cursor position to an index required by those FM and should not be changed to read multiple records.

Hi Raymond,

I am trying to execute as stated above.(exactly-1).

If I select or mark any records in the table control then I can read them in my module pool.

But my requirement is without marking or selecting any records I want to fetch all the records and save them.

Thanks and Regards,

hi kawish,

Why it is not working:

Is your code same as this in the PAI.

read table itab into wa index tcontrol-CURRENT_LINE.

    ......................

    modify itab from wa index tcontrol-CURRENT_LINE.

endif.

Hi Abdul Raheem,

Yes the code is same.

unable to fetch the data from either of the above statements.

Can you share your source code?

so that it can be checked and advised accordingly.

[RaymondGiuseppi]

If you remove the ON CHAIN-REQUEST then internal table will always been refreshed from screen (even if not useful at all...°

But insure the FIELDS statements are executed after reading data from screen, else they will be overriden by previous values in the READ TABLE statement if you don't manage two work areas one for READ TABLE and one for FIELDS read from screen.

Hi Kawish,

In PAI event between loop and endloop. create module and u will get data in wa..
