Module pool table control data validation

[Former Member]

Hi Experts,

I have a question on data validation in table control.

There is a table control on the input screen where the user needs to enter data.

The system should validate the entered data and throw error message if there is wrong value against each field.

When I clicked on enter after entering the data in table control, it is getting disappered.

Please suggest to resolve this.

Thank you.

Regards,

Sri

Normally the flow logic of your screen should look something like this (cfr the loops). I'd start by making sure the loop in the PAI is present as well.

Ex:

PROCESS BEFORE OUTPUT.

* MODULE STATUS_0100.

  module data_retrieval.

  loop at it_ekko into wa_ekko with control TC100.

    module populate_screen.

  endloop.

*

PROCESS AFTER INPUT.

  loop at it_ekko.

  endloop.

* MODULE USER_COMMAND_0100.

Hi

Please check the field properties and mark the output field checkbox .Now try the same. Let us know if you still have issues.

Also please check the below previous discussions relevant to this

How did you code your PAI, does it look like

process before output.
  MODULE pf_status_and_attr.
  LOOP AT itab INTO record with control ctrl cursor ctrl-current_line.
    MODULE record_fill. " fill data if required (e;g. not TABLES)
    MODULE record_attr. " modify screen attributes for this line
  ENDLOOP.

process after input.
  module user_command at exit-command.
  LOOP AT itab.
    MODULE reload_record. " if reload previous data required (e.g. not displayed fields)
    chain.
      field record-field1.
      field record-field2.
      module record_check on chain-request. " if PAI NE PBO
      MODULE modify_itab.
    endchain.
  ENDLOOP.
  MODULE user_command.

Hi,

The table control initially is an empty one.

User may enter values in any number of rows and correspondingly each row needs to be validated for two fields.

I am unable to retrieve the data entered by user into the internal table.

@Raymond,

The code almost looks like the way you shared other than chain-request.

FIELD fld1 MODULE check_fld1.

Appreciate your help.

Thanks,

Basically from MODULE reload_record. til MODULE modify_itab  you will append new or update existing records.
