ABAP WebDynpro Fields Set Invisible Status

Hi All,
I am new to this ABAP WebDynpro programming, i have requirement, based on IF conditions i need to set my fields In-Visible and Visible mode,
ex:
IF XXXXXX
THEN FIELD VISIBLE
ELSE XXXXXX
FIELD IN-VISIBLE
ENDIF.
Thanks in Advance.
Thanks and Regards,
Abhi.

Hi Jagadish,
                 Thanks for your prompt response, based on your instructions i did like below
I created F_Visible in Context with type WDY_BOOLEAN and i given default value to X, then i bind this value to my input fields, after the using WebDynpro Code wizrd i called F_Visible attribute, the below one is my code, please correct me if any thing wrong.
IF(Condition)
   DATA lo_el_context TYPE REF TO if_wd_context_element.
   DATA ls_context TYPE wd_this->Element_context.
   DATA lv_f_visible TYPE wd_this->Element_context-f_visible.
get element via lead selection
   lo_el_context = wd_context->get_element( ).
@TODO handle not set lead selection
   IF lo_el_context IS INITIAL.
   ENDIF.
@TODO fill attribute
lv_f_visible = 1.
set single attribute
   lo_el_context->set_attribute(
     name = `F_VISIBLE`
     value = lv_f_visible ).
xxxxxxxx
ELSE
lv_f_visible = 'X'.
    set single attribute
    lo_el_context->set_attribute(
      name = `F_VISIBLE`
      value = lv_f_visible ).
when i was testing my applicaiton i am getting   Access via 'NULL' object reference not possible.
could you please help on this setting if i did any thing wrong.
Thanks in Advance.
Thanks and Regards,
Abhi Ram.

How to set portal authorization in ABAP Webdynpro application

Hi All,
Do you have an idea how to set the visibility for Group UI element based on the Portal user authorization in ABAP Webdynpro , for example if the portal user A(or group A), logins into the portal on click of the ABAP Webdynpro IView then we need to set invisible (hide) the Group UI element in webdynpro ABAP Application.
Do you have any sample code on the same to handle the portal authorization in Webdynpro ABAP?? , please let me know if couldnu2019t understand this requirement or my explanation
Thanks,
PortalUser100

Hi Kris,
Thanks for your reply.
Like however we passed the UserID, can we pass Group ID also to the ABAP Webdynpro application??
Can u get me other things, how to copy of the existing component and i want to give the new name for the component and there i need to modify, i dont want to disturb original component before copy...let me know the procedure for the same??

ABAP code to set Infopackage Monitor to "RED" status?

Hello,
I have an Infopackage that is using ABAP code to determine the selection values dynamically for an Infoobject during the load (Type: 6 ABAP routine). We have built in customer error checking on the selection values based on our requirements.
In the event of an error I need to do the following:
    -Set the 'Total' and 'Technical' color status to "RED" in monitor.
    -Define custom error message in "Status" tab of monitor for load.
Does anyone know how to accomplish this? Links to an example or previous thread will be appreciated.
Thank you,
Brian

The status of a particular request is stored in the table RSREQDONE. You can have an abap code to modify the entries of the field TSTATUS (technical status of the request) in this table for the given request number.
Example:
Value of @5B@ for this field denotes that this request is successful (GREEN)
FYI, I am not sure how recommendable this process is coz I never implemented before.

Set color alv output cell abap webdynpro

Hi Guys ,
i wanted to set the color of some cells in alv output to red in ABAP WebDynpro.
i am using the salv_wd_table.
any piece of code is appreciated.
thanks,
Bobby.

Bobby,
If let's say you are build a ALV table to output 'SFLIGHT' table, and you want PLANETYPE '747-400' to be displayed in green, and PLANETYPE '146-200' displayed in red.
Also, let's just say, you already had a context node 'SFLIGHT_NODE' that is mapped to the external node 'DATA' of your ALV.
Now:
1. you need to modify the context node 'SFLIGHT_NODE' to add an attribute -- say 'CELL_COLOR' of type 'WDY_UIE_LIBRARY_ENUM_TYPE' -- to the SFLIGHT_NODE (note, you need to delete 'DICTIONARY structure' that is bind to the 'SFLIGHT_NODE' node, otherwise, you will not be able to create addition attributes)
After, you will have something like this for your context node .
CONTEXT
    --> SFLIGHT_NODE
> CARRID
> CONNID
> FLDATE
> PRICE
> PLANETYPE
> <and any other attributes you had pulled from SFLIGHT)
> CELL_COLOR (TYPE WDY_UIE_LIBRARY_ENUM_TYPE)
2. In your supply function to the 'SFLIGHT_NODE', you now need to supply the data to this newly added attribute:
METHOD supply_sflight_node .
** data declaration
DATA:
    itab_sflight_node            TYPE if_componentcontroller=>elements_sflight_node,
    stru_sflight_node            LIKE LINE OF itab_sflight_node.
** read sflight data
SELECT * FROM sflight INTO CORRESPONDING FIELDS OF TABLE itab_sflight_node.
** populate the 'CELL_COLOR' field
LOOP AT itab_sflight_node INTO stru_sflight_node .
    IF stru_sflight_node-planetype = '747-400'.
      stru_sflight_node-cell_color = CL_WD_TABLE_COLUMN=>E_CELL_DESIGN-GOODVALUE_DARK .
     ELSEIF stru_sflight_node-planetype = '146-200'.
      stru_sflight_node-cell_color = CL_WD_TABLE_COLUMN=>E_CELL_DESIGN-BADVALUE_DARK .
    ELSE.
      stru_sflight_node-cell_color = CL_WD_TABLE_COLUMN=>E_CELL_DESIGN-STANDARD .
    ENDIF.
    modify itab_sflight_node from stru_sflight_node.
ENDLOOP.
** bind all the elements
node->bind_table(
    new_items = itab_sflight_node
    set_initial_elements = abap_true ).
ENDMETHOD.
3. Now, you need to obtain the configuration model of the ALV and config it before display. (say you have an method does this 'init_alv_table_settings', and it is called from your view's wddoinit() method)
METHOD init_alv_table_settings .
DATA: l_ref_cmp_usage TYPE REF TO if_wd_component_usage.
l_ref_cmp_usage =   wd_this->wd_cpuse_alv_table( ).
IF l_ref_cmp_usage->has_active_component( ) IS INITIAL.
    l_ref_cmp_usage->create_component( ).
ENDIF.
DATA: l_ref_interfacecontroller TYPE REF TO iwci_salv_wd_table .
l_ref_interfacecontroller =   wd_this->wd_cpifc_alv_table( ).
DATA:
node_sflight_node                   TYPE REF TO if_wd_context_node .
node_sflight_node = wd_context->get_child_node( name = if_flights_view=>wdctx_sflight_node ).
CALL METHOD l_ref_interfacecontroller->set_data
    EXPORTING
      r_node_data = node_sflight_node.
** get ConfigurationModel from ALV Component
DATA:    lr_table TYPE REF TO cl_salv_wd_config_table.
lr_table = l_ref_interfacecontroller->get_model( ).
** change the color of the cell
DATA: lr_column_settings TYPE REF TO if_salv_wd_column_settings.
DATA: lr_column TYPE REF TO cl_salv_wd_column.
lr_column_settings ?= lr_table.
lr_column = lr_column_settings->get_column( 'PLANETYPE' ).
DATA: lr_input_field TYPE REF TO cl_salv_wd_uie_input_field.
CREATE OBJECT lr_input_field EXPORTING value_fieldname = 'PLANETYPE'.
lr_column->set_cell_editor( lr_input_field ).
lr_column->set_cell_design_fieldname( value = 'CELL_COLOR' ).
ENDMETHOD.
Compile and activate your code.

Dynamic screen field layout - ABAP webdynpro

Hi,
I am rather quite new to ABAP webdynpro - one of my requirements is that based on a Custom table (so to say a custom built customizing table) I need to display fields - the Customizing table could say that for region America - we need the following fields to be supressed, the same set of fields for Japan could be Mandatory, and for Latin America could just be display only.
Is there anyway this could be acheived in Webdynpro (ABAP) - I presume that the supressed fields for America region will not be displayed but instead the common fields for America and Japan would be out of sync as far as screen layout is concerned. An ideas or guidance on how to accomplish this would be greatly appreciated.
Regards....

Hi,
you can loop on your table which gathers all the fields in it, add an attribute to your
table stating the required or not parameter and adding it to the 'state' parameter in
the new_inputfield method.
In the Wiki I added a page for dynamic UIelement creation based on DDIC properties
(wiki is down, so i don't have a link to it)
or you can visit these logs by Thomas Szues:

Can ichat set my status to invisible as soon as i log on?

Is there a way to automatically set my status as invisible or away when I first logon to ichat?

Yes.
With iChat Open go to the Preferences > General Section.
Untick the item about Changing the Login to Available on Start up.
In the Accounts preferences untick the Box (whilst logged out) that says Login Automatically (Account Info tab)
Now when you start iChat it will not log in a Buddy List.
You can then set Statuses and such and manually log them in.
Alternatively you can use the Preferences > General section to show the Status iocn (Menu Bar icon)
You can then use this iCon to Login the front most Buddy list with the status you want.
I saw a post recently about also opening iChat with a modifier key but I cannot remember which one it was.
(this did the same thing)

Error Handling in tables using ABap Webdynpro

Hi All,
I am new to this ABAP webdynpro programming. I have a small question. I am using a table control in one of my iview. I need to check some validations on some columns of this table. Let's say I have a table with 3 columns A,B and C.
Case 1 : Whenever any user enters values in C which is greater than A i want to raise an error message saying "The Value is greater than A". The user shouldn't be allowed to enter anyother inputs before correcting the same.
OR
Case 2: If the user enters 10 rows in the table and the 5th row contains the error. How can i highlight that row or field which contains the error.
Your inputs will be valuable to me.
Regards,
Pravesh.

Hi,
Get the elements of the node for which you table is bound.
Loop through the context element set.
get the record for that context attribute and check the column A and column B value and throw
the error using the report_error_element_message when there is error.
Check this sample code -
DATA:
    lt_attr_list type STRING_TABLE,
    ls_attr_list type string.
ls_attr_list = column name.
append ls_attr_list to lt_attr_list.
clear ls_attr_list.
ls_attr_list = column name.
append ls_attr_list to lt_attr_list.
clear ls_attr_list.
DATA: lit_elementset type WDR_CONTEXT_ELEMENT_SET,
lis_element type ref to IF_WD_CONTEXT_ELEMENT,
ls_data type <<strucure type>>.
    CALL METHOD <<nodename>>->GET_ELEMENTS
      RECEIVING
        SET = lit_elementset.
    LOOP AT lit_elementsetINTO lis_element.
lis_element->get_static_atributes->
importing = ls_data.
if ls_data-columnC GT ls-data-columnA.
lr_msg_manager->report_element_error_message->
message_text = 'Column C canot be gretaer than column A'
element = lis_element
attributes = lt_attr_list <<Populate the attributes table for which errors are to be shown>>
endif.
clear: ls_data, lis_element.
ENDLOOP.

Validations in ABAP webdynpro

Dear friends,
I am trying to find out what is the simplest and best way to have validations in an ABAP webdynpro. There are a bunch of fields in a view in one of the webdynpros that iam working on. I would like to set up validations to some of the fields. I am trying to find out if there is a standard action or method that will help me achieve this; or would i have to create a new class for this.
Any help is greatly appreciated.
Thanks

Your opinion on: BSP or Java Webdynpro or ABAP Webdynpro?

Could you please give me your opinion on the business scenario we have here:
We are implementing SRM 4.0 with backend R/3 4.6C, WAS 6.4 and Portal 6.0. SRM has its typical shopping cart applications mainly for procurement and the workflow trail displaying the approval. The client wants us to build a few custom forms on the web frontend of SRM (or may be in Portal). The idea is to store these forms and display when needed with the status info just like a shopping cart.
<b>Now the requirements for these forms are as follows:</b>
1. These forms will have multiple fields which need to have the F4 kind of help. (the F4 options will reside in SRM or R/3)
2. The form should have some kind of a ALV grid (autoexpanding feature) which will allow the user to put in multiple line items so that they could submit more items on one form.
3. Users need to be able to attach a spreadsheet to the form which should not be editable once the form is submitted. The attached spreadsheet should be stored. (We are planning on using Archivelink Filenet for this)
4. Upon submission, a workflow will be kicked off as per the defined Org structure for approval of the form.
5. After submission, the user should be able to go and view the approval status of the form and also print the summary of the values that he entered in the form. (may be a smartform could be provided for this)
We looked at different options to accomplish this task:
<b>BSP:</b>
Creating BSP pages and giving access as links to the user on the webfrontend of SRM. Now, if we go the BSP route, we need to develop in SRM as the R/3 4.6 c does not have BSP development capabilities. If we take this approach, I am not sure if all the above requirements (specially like attaching spreadhseets) will be met with BSP pages.
SAP Webdynpro Java:
It seems that the Webdynpro is easier to use because of the graphical tools available. But the only problem if we go this route is that we will have to find a java guy.
SAP Webdynpro ABAP:
We currently have WAS 6.4. As per the documentation, the ABAP Webdynpro development tool is available from NW04s onwards. So, we are still not sure if we could use it. But, we want to push towards upgrading if necessary. Being an old time ABAPer, developing ABAP Webdynpro seems do-able. (i know it may not be that easy).
Last but not the least, DIALOG Program:
Creating a dialog program in R/3 or SRM seems fairly simple. Then, an iview could be created on the portal for this transaction, though at this point I am not sure how a spreadsheet could be attached and stored within a dialog program.
The creation of the workflow may not be that bad after the original form is designed. The graphical display of the approval trail might be difficult, but we might get away with a report for that. For printing the details of the form, I guess I could develop a smartform and put out a button on the screen to print it out in the display view.
Could you please give me your opinion / best approach for accomplishing this task, keeping in mind the complexities of these new dimension products?
Thanks
Sri

I would say that all four solutions to solving your tasks are technically feasible. Here are some thoughts that I had however:
First ABAP Webdynpro: it is true that ABAP webdynpro is only available with Netweaver04s. 04S is still in ramp-up which means that only a subset of the customer base is allow to implement it. It will not become generally available until later this year (check the service marketplace for current release estimates). That being said, it probably elimintes WDA as a possiblity for your project unless you are will to wait and to upgrade.
However having worked with WDA for a while it is probably the best tool to custom develop what you describe. It has excellent built-in F4 value help. It also has a damn fine ALV grid implementation. The spreadsheet could be just as simple as file upload in binary or your could try your hand at office integration. Finally for the form you could use Adobe Interactive Forms which also has very nice integration into WDA.
Now to Dialog Programming: You could of course use dialog programming. It seems a little bit of a waste to custom build something so large if WDA is in your near future. There are obvious disadvantages (little OO structure, no MVC, etc). You would have ALV grid, office integration and of course F4 help. You could still use Adobe forms if you implement this on the 640 system. However there are integration points with dialog and Adobe Interactive Forms. You could still use printed forms however. If you did the dialog program on the 640 system, you could use the integrated ITS to expose it to the web. The integrated ITS in my experience has quite nice performance although the look and feel remains just like the SAPGui.
The Java Webdynpro route: Well you hit the nail on the head - if you don't have a Java programmer already and you don't have the bandwidth to invest in learning Java, this can be a problem. The Java Webdynpro environment is quite nice. There are some things I like better than ABAP and some things that ABAP is defintely still better at. However when it comes to heavy integration with an ABAP backend - ABAP Webdynpro is still the way to go. Java Webdynpro does have a help feature (OVS), but it isn't "for free" or nearly as nice as the ABAP Webdynpro (perhaps it will get there some day). That is one of the major advantages of WDA - its closeness to the business data brings several framework advantages like F4 and field help. WebDynpro Java in 640 also doesn't have an ALV grid implementation. I am sure that this is something both environments will eventually have, but right now ABAP has the advantage. On the other hand, Webdynpro Java has equal support when it comes to office integration, file upload, and Adobe Forms support. You would have a more difficult time integration SmartForms however.
Finally we come to BSP. Honestly if I were in your position I would probably choose BSP (unless you could wait for the ABAP Webdynpro upgrade). You could build a nice MVC OO application using BSP (stateful or stateless). The BSP product is mature and quite well documented thanks to SDN. You have the BSP Extensions which when used in Design2003 use the Unified Renderer. That means that your output will look nearly identical to the same UI elements in Webdynpro. Also BSP supports portal integration (session management, eventing, and themes).
The downside to BSP is that it isn't a full framework (also one of its advantages). You can insert all your own html and javascript (unlike webdynpro). But this also means that SAP doesn't delivery as many framework services. For instance there is no ALV or Value Help. There is no Office Integration or Adobe Forms integration. There is some farily good Smart Forms integration. Now the upside- many people have already hit these limitations and overcame them. In the weblogs on SDN and in a certain SAP Press book (cough, cough) you will find out of the box solutions for many of these problems. You can find ready to use solutions for Adobe Integration, Office Integration (using Microsoft Office Web Controls), and F4 help. It will mean investing a little more time up front to get this "home grown framework" up and running - but it is perfectly feasible.
There is a learning curve to all these new technologies however. This sounds like an abmious project. I wouldn't want to try and tackle this project in any of these technologies if I was new to them. With Webdynpro or BSP - consider giving yourself time to learn the environment and cut your teeth on some demo apps before jumping into such a huge development.

ABAP WebDynpro, Interactive Form, and Repeating Subforms

Hi Everyone,
I have a very simple Interactive Form called from ABAP WebDynpro.
Main_View Context:
Node u2013 FORM.
     Cardinality 1..1
     Selection 0..1
     Initialization Lead Selection u2013 X
Node u2013 SPFLI
     Dictionary Structure - SPFLI
     Cardinality 0..n
     Selection 0..1
     Initialization Lead Selection u2013 X
Attributes from SPFLI u2013 CARRID and CONNID
View contains an Interactive Form and a u201CSaveu201D button.
Form = Z_TABLE_TEST_FORM, Interface = Z_TABLE_TEST_INT u2013 created through forward navigation in Layout so uses XML interface.
Button u201CSaveu201D has the following code:
METHOD onactionsave.
DATA lo_nd_form     TYPE REF TO if_wd_context_node.
DATA lo_nd_spfli    TYPE REF TO if_wd_context_node.
DATA lo_el_spfli    TYPE REF TO if_wd_context_element.
DATA ls_spfli       TYPE wd_this->element_spfli.
DATA ls_element_set TYPE wdr_context_element_set.
lo_nd_form = wd_context->get_child_node( name = wd_this->wdctx_form ).
lo_nd_spfli = lo_nd_form->get_child_node( name = wd_this->wdctx_spfli ).
ls_element_set = lo_nd_spfli->get_elements( ).
IF lo_nd_spfli IS NOT INITIAL.
    lo_el_spfli = lo_nd_spfli->get_element( ).
    IF lo_el_spfli IS NOT INITIAL.
      lo_el_spfli->get_static_attributes(
        IMPORTING
          static_attributes = ls_spfli ).
    ENDIF.
ENDIF.
ENDMETHOD.
On the Interactive Form, u201CPage1u201D is a main page. u201CTableParentu201D is a SubForm, flowed layout, in accessibility tab set to u201CTableu201D, and is bound to u201C$record.SPFLIu201D.
u201CDATAu201D is a SubForm under "TableParent", Positioned layout, in accessibility tab set to u201CBody Rowu201D, and is bound to u201CDATA[*]u201D.
Carrid and Connid are both Text Fields bound to Carrid and Connid, under "DATA".
I also added the Insert/Remove/Reposition buttons, but deleted the two reposition buttons.
The idea was to be able to add 4-5 Carrid/Connid pairs.
When running this, as configured above, then none of the data entered in the form makes it through to the Elements. If the context is changed to make the Cardinality 1..n, then a single Element is added u2013 but not the remainder.
What needs to be done to get this to work?
Many thanks
Jack

Hi Reema,
None. For all other fields, they are bound to the context, so the transfer is automatic.
These repeating fields are also bound to the context, but it appears that an element needs to be created for every repeating form. How can this be done from the form?
Cheers
Jack

BRFplus + BPM + ABAP Webdynpro Architecture

Hi Gurus,
We are setting up Data Governance model in our company. As a part of this, we are currently evaluating various options. We are also considering BRF plus solution. Some of our high level requirements are as follows
1.     Break SAP transactions for Material Master and regroup the fields according the new business processes in different screens in web front end (possibly ABAP WebDynpro)
2.     Set up a workflow solution for new business processes (possibly BPM or Business Workflow)
3.     Integrate Business rules and validations, data checks and so on using BRF plus in to the workflow.
What that means is that whenever users make changes to the Material master Data in web front end, then a workflow is triggered and rules are applied to the data before the data is changed/created.
My questions are as follows
1.     Do we really need all these 3 components namely ABAP Webdynpro, BPM or Business Workflow and BRFPlus to achieve what we want to achieve? Or we can achieve this without having one of the components mentioned above?
2.     If yes or no, how the architecture should look like?
3.     How do we integrate these techonologies (which features of what component)
4.     Any examples you can share?

I don't see the need of web dynpro or BPM if you only want extra data validations.
You can integrate extra rules into your regular system as is using BRFplus for extra validations.

Sorting issue in ALV ABAP webdynpro

Hi All,
We are displaying the data in ALV format using ABAP webdynpro.
The issue here is sorting the values. The field is the character field, as the field may contain character or numberic values.
When we sort a set of values in ascending order, the values are sorted wrongly.
Example values sorted in ascending order:
11055
11260
5662
8697
9984
The above values are sorted wrongly. Is this a standard limitation of webdynpro ABAP or do we have any support class or setting available to solve this issue.
Please help.
Regards,
Vijay

Hello Vijay
of course its not a limitation, you can sort it either ways.
Check the following link
http://help.sap.com/saphelp_nw70/helpdata/en/e9/e5eb40c4f8712ae10000000a155106/content.htm
you can use the following classes
Set sort Direction -
CL_SALV_SORTS meth: ADD_SORT (Parameter SEQUENCE)
CL_SALV_SORT meth: SET_SEQUENCE
Get sort direction
CL_SALV_SORT meth: GET_SEQUENCE
hope this helps!!
