Validate ALV entry

Hello.
I'm using an ALV display with a custom field catalog to allow a user to edit data via the ALV display (certain fields).
I create my container and fieldcatalog in the PAI of my screen and use CALL METHOD grid1->refresh_table_display to display it, I can edit the contents of the table displayed in the ALV just fine. Now I want to validate the edits as they happen and pop a message and disallow the edit by a rule/validation I define. Can someone show me how/where/what to insert a validation routine into this?
Thanks!

Handle the data_changed event in the grid.
Whenever you make changes in the data in ALV Grid this event would be triggered. Here you can perform additional validations that you may need to perform.
code METHODS handle_data_changed
FOR EVENT data_changed OF cl_gui_alv_grid
IMPORTING er_data_changed.[/code]
Implementation:
code METHOD handle_data_changed.
PERFORM validations USING er_data_changed.
ENDMETHOD.[/code]
codeFORM validations USING er_data_changed TYPE REF TO cl_alv_changed_data_protocol.
DATA: ls_good TYPE lvc_s_modi.
DATA wa LIKE LINE OF lt_good_cells.
CALL METHOD g_grid->register_edit_event
EXPORTING
i_event_id = cl_gui_alv_grid=>mc_evt_modified.
LOOP AT er_data_changed->mt_good_cells INTO ls_good.
CASE ls_good-fieldname.
WHEN 'FIELDNAME'. "Your fieldname
CALL METHOD er_data_changed->get_cell_value "Get the changed value
EXPORTING
i_row_id = ls_good-row_id
i_fieldname = ls_good-fieldname
IMPORTING
e_value = temp. "Your temp variable
"Make your validations here.
ENDCASE.

Where to validate ALV entries

We have an editable ALV grid. Where is the right place to call our validations from?
Following validation, we also want to (programattically) update some cells in our grid.
Where is the right place to place the updates?
Thanks

Hi,
You will have many options to validate the ALV entries, based on your requirement you need decide.
Let us assume if you want to validate on each cell ->then once user enter some value on cell ask them to enter, you need to validate these cell values on_enter event on alv functionality.
If user want to validate once enter all the cells...then you need to provide some button or use the standard button CHECK on ALV application tool bar..under the Action button youneed to validate.
Let me know if you need more clarfications on this.

Naresh.

Reset ALV entry in display

Hello.
I'm using an ALV display with a custom field catalog to allow a user to edit data via the ALV display (certain fields).
I create my container and fieldcatalog in the PAI of my screen and use CALL METHOD grid1->refresh_table_display to display it, I can edit the contents of the table displayed in the ALV just fine. I can validate each entry the user makes using the register_edit_event and use CALL METHOD er_data_changed->get_cell_value to get the user data as they enter and I can then validate the entry against my custom rules. My issue is that if the user violates the rules I defined in my code I would like to reset the entry. What method can I use to do this. My code for validation is below.
CLASS lcl_event_receiver IMPLEMENTATION.
METHOD handle_data_changed.
    DATA: ls_good TYPE lvc_s_modi.

Thanks!!

I have located the answer.
When I do my validation routine if my error criteria has been reached I through a flag and then execute the method "modify_cell" to reset it to whatever value I choose.
            CALL METHOD er_data_changed->modify_cell
                EXPORTING
                      i_row_id = ls_good-row_id
                      i_fieldname = <my fieldname>
                      i_value = <value to reset field to>.

Validate Journal Entries using write back BADI (UJR_WRITE_BACK)

Hi Experts
I need to validate journal entries such that the total credit and debit postings for each COMPANY is equal. Also I need to do the same validation by PROFIT CENTER. After doing a bit of research I found out that the best way to do it is by coding it in the write back BADI.
Has anyone faced such a situation before? Is there any better way to do it? Can anyone share the code?
Thanks
Edited by: Shisher Chakrabarty on Mar 1, 2012 10:22 AM

Hi Shisher,
Please check the below guide for Write Back BADI. The doc has also got the source code for the same.

Validate form entries: does java support regular expressions?

How to validate an entry in a table?

I have a (single column) table view linked to an NSArrayController that has a custom class definition as its 'Class Name'. I also have KVC compliant methods to populate the array controller within my 'model'. I can see the 'countOf...' and 'objectIn...AtIndex' methods being called and the table contains the correct data.
I have the 'Validates Immediately' option set on both the table column binding and the controller content array binding.
My problems come when I alter the contents of an entry in the table. Firstly, the only 'validate...:error:' method that is called is on the custom class for the field that is updated.
Secondly, the 'insertObject:in...:AtIndex' and similar (especially the 'replaceObjectIn...AtIndex:withObject:') methods are not called.
I have checked and rechecked that the KVC names include the correctly capitalised name of the class.
How can I get the validation (and other) routines to be called?
Thanks

Possible to validate data entries during Digital Signature?

I have a form that was built from scratch using Adobe LiveCycle Designer ES 8.2. I also have Adobe Acrobat Pro 9.3.2. (WinXP)
I see numerous articles online related to validating user input prior to data submission for an online form via a Submit button, however, I am trying to figure out how to implement the same sort of data validation during the signing of a particular digital signature field in an offline pdf form. Simply, I want to perform data validation during a digital signature instead of when user presses Submit button.
Here's my use-case:
1. Form Originator fills out a large number of data fields and signs form via a CAC cert.
2. Another person will review, possibly edit/add data, and sign another signature block with CAC.
3. Then there is one more final CAC signature on the form before it is completed and then emailed to the right folks for processing.
4. I would like to be able to enforce the population of several Mandatory data fields (at least one Radio button and one text input, possibly others) before the 3rd signature can be applied to the document.
Again, I need to emphasize this is all happening in an offline form, no data submission or database back-end. Also, everything with the digital signatures (and locking up fields afterword) works totally fine, just interested in adding Data Validation capability during Digital Signature.
I am in no way a javascript expert, but I can probably learn from a good example. Any help or guidance is very much appreciated. Thanks...

If you are using SignatureField in the form then you will get two events preSign and postSign which you can use to validate the field input just like you do with a Submit button.
Thanks

Validate element entry at Element Entry Screen and BEE

Hi,
I would like to incorporate some validation at both the Element Entry screen and Batch Element Entry.
The validation rule is user is only allow to enter one element between Element A and Element B, they are mutually exclusive.
1) When user enter Element A, Element B should not exist in Element Entry screen.
2) When user enter Element B, Element A shoudl not exist in Element Entry screen.
The entry point for the element can be done via
1) loading via BEE screen
2) entry via Element Entry screen
Thus, the validation rules should apply at both the entry point.
I have tried to used the user hook via the pay_element_entry_api, however, it is not working (meaning no validation take place).
And I also notice that the form PAYWSMEE.fmb is not using the pay_element_entry_api but is using hr_entry_api.
Appreciate advise on this as this validation is really important to the clietn to ensure correct payment.
Thanks,
ShiauChin

Thanx Sharath for your quick response.
But I have run QuickPay for that employee.
After running QuickPay the input values names are coming into element entry value screen.
But it is not showing the value corresponding to the element input value names.
Thanks,
Pankaj Kedia

F4 help in ALV grid, how to check the entries?

Hello,
I have created F4 help on the cells in a ALV using OO ABAP. The F4 Help works fine and the user can select the entries from it. BUt in F4 help, the user can manually enter values also.
I want to either disallow the user the enter values manually or validate his entries and ask him to choose from F4 only.
How to achieve this??

Use this in Top Include

Dynamic ALV columns in Web Dynpro ABAP

Hello masters:
Does anybody know how to build an ALV with dynamic columns in a WD4A?
I know how to make an ALV with a dynamic context node (dynamic DDIC structure), but it isn't the problem. First, I need to validate data entries, and then I will know how many fields I have to show.
I've been reading about interface IF_WD_CONTEXT_NODE_INFO. I think some of its methods can be useful to me. Can you help me to solve that?
Thanks.

Hi Rodrigo,
There are two ways for it:
1) Creating an attribute dynamically under the Staticly defined node.
2) Creating a new node dynamically with your desired columns in it.
I am explaining the second process, Here it as follows:
1. Create a WDC, and use the component SALV_WD_TABLE.
2. Create a node in the context to store the defined strucutre name.
3. Read the node and set the structure name to that node from which you want to get the columns.
4. Use this structure name and create a new node dynamically.
5. Set the data to this dynamically created node.
6. Set this context node to ALV.
Here is the sample code:
To get the strcutre from where you want to fecth the fields.
tabname_node->get_attribute( Exporting name = 'TABLENAME'
                              Importing value = tablename ).
translate tablename to upper case.
*create sub node named TEST1 of structure (tablename)
cl_wd_dynamic_tool=>create_nodeinfo_from_struct(
   parent_info = rootnode_info
   node_name = tablename
   structure_name = tablename
   is_multiple = abap_true ).
DATA: stru_tab type ref to data.
field-symbols: <tab> type table.*Create Internal Table
create data stru_tab type table of (tablename).
assign stru_tab->* to <tab>.*Get table content
select * from (tablename) into corresponding fields of table <tab>.*get instance of new node
dyn_node = wd_context->get_child_node( name = tablename ).*Bind Internal table to context node.
dyn_node->bind_table( <tab> ).*instantiate alv component
data: l_ref_cmp_usage type ref to if_wd_component_usage.l_ref_cmp_usage =   wd_this->wd_cpuse_alv( ).
if l_ref_cmp_usage->has_active_component( ) is initial.
l_ref_cmp_usage->create_component( ).
endif.*pass context node to alv
data: l_ref_interfacecontroller type ref to iwci_salv_wd_table .
l_ref_interfacecontroller =   wd_this->wd_cpifc_alv( ).
l_ref_interfacecontroller->set_data( dyn_node ).
Hope it helps..
Good day!

How to validate Quantity field in TV - Inputfield ?

Hello All,
        I'm using a table view to show the output .
IN this table view I made 2 fields as Input fields.
Both the fields are Quantity fields.
Now when the user enters a value in this Quantity field I want to validate it with respect to it's units .
How can I do that ?
In my case if the user enters correct value it works but when he enters a wrong value my BSP is going for a dump.
I tried to debug the<b> LIPS table</b> to verify how SAP was handling this checking for the field <b>LFIMG</b>. But there there is a statement called chain --endchain.
SO there is no chance for debugging.
My code is as follows :-
        LOOP AT gt_final INTO wa_final.
          CLEAR: gv_row,lv_qty,lv_string,gv_len,gv_cell_id1.
          gv_row = sy-tabix.
          gv_len = STRLEN( gv_row ).
          gv_len = gv_len - 1.
* Modify the Third Column
          CONCATENATE 'INB01_TV_ID' '_' gv_row(gv_len) '_' '3' INTO gv_cell_id1 .
          lv_string = request->get_form_field( name = gv_cell_id1 ).
          WRITE lv_string TO lv_qty UNIT wa_final-units.
          CLEAR :wa_final-del_quantity.
          wa_final-del_quantity = lv_qty.
          MODIFY gt_final FROM wa_final TRANSPORTING del_quantity.
        ENDLOOP.
Can anyone tell me how to validate the entry for the Quantity filed ?
Regards,
Deepu.K
I have one more Question .
Whenever BSP goes for a dump in this case I want to handle this by a message .
Is it possible ?

Hello Raja,
       I want to validate the entry in the QUantity field with respect to the Unit of the Quantity.
I.e say for example I have a unit as PC (pieces) then the quantity must be only of thousands,lakks and so..on......but not in points i.e a piece quantity must be full either 200 ,2 lakhs or 2 pieces but not 2.5 pieces.
SO now if the user enters 2.5 it's a wrong value as the quantity for the Unit PIECES can't have half-piece. (2.5 = 2 + 0.5) .SO i want to validate this .
I hope I'm clear.
How should I do ?

How to suppress 'spurious' update events where the entry is identical

We often have clusters with event listeners on reference data caches. These caches are refreshed by calling putAll() to update values efficiently. Although this is efficient, and keeps refresh code simple, many unwanted 'spurious' update events are generated. Spurious in the sense that in most of update events the old and new values are the same.
We considered using a MapTrigger to suppress these uninteresting update events. The problem is how to implement a 'veto' in the MapTrigger.process method. What we'd like to do from a trigger is:
if (old value == new value)
ignore new entry
else
process, enrich, or validate new entry as desired...
end ifWe'd like a clean way to signal from a MapTrigger that an entry should be ignored (rather than rejected). The Javadoc shows two possibilities:
*(1)* undo the pending change by resetting the entry value to the original value obtained from MapTrigger.Entry.getOriginalValue();
*(2)* reject the pending change by throwing a RuntimeException, which will prevent any changes from being committed, and will result in the exception being thrown from the operation that attempted to modify the map
Of these *(2)* Causes a put() failure in the client. That is appropriate for something like a validation failure, but not for simply ignoring an unwanted update. Option *(1)* unfortunately generates an update event!
Our current workaround is a MapEventTransformer to suppress the spurious updates:
public class UpdateSupressionTransformer implements MapEventTransformer {
/** Avoid sending an update event if the value is unchanged */
public MapEvent transform(MapEvent e) {
    if (e.getId() == MapEvent.ENTRY_UPDATED) {
      if (e.getNewValue().equals(e.getOldValue())) {
        return null;
    return e;
}This works well but requires client code to register event listeners correctly. It also means that the unecessary change is still generated in the cache. For example a cache stores will be called needlessly.
Can a feature be considered to allow a clean way for identical updates to be ignored, or to not generate events?
Ideally this would be before the update is made - like a trigger. It seems a pity the MapTrigger design does not allow this.
Such a feature would allow simple cache refresh logic using putAll() - without having to check for deltas - avoiding large numbers of unwanted update events. We think this is likely to be a common requirement.
Cheers,
phil

Please do the needful how to do it.If you want to validate at entry level then use When-Validate-Item trigger and check the input and show message. Like
If :quentity <0 then
message('do not enter negative value');
message('do not enter negative value');
raise form_trigger_failure;
end if;Why u open same thread again ? not closing one.. check this one
