Error While processing request

[Former Member]

Hi Experts

I have Created Web Dynpro Application With Two Views

1.Search for Flights

2.flights Display

my Input parameter is CONNID and CARRID

but When I am executing the Application i am able to put the input parameters after while we executing the Search button it is showing the below error

The following error occurred in system BQ1 : Parameter CARRID contains an invalid value .

The error occurred on application server inbiw_BQ1_00 and in work process 0 .

The termination type was: RABAX_STATE

Tip:

You should always use "Web Dynpro Code Wizard Button (CTRL+F7)" in the toolbar. Harry Potters magic wand.

[former_member211591]

An easier solution is to correct the structure on the other side, USE THIS instead of my former post:

method HANDLEFROMSEARCH .

DATA :
IT_FLIGHTS TYPE wd_this->ELEMENTS_INPUT,      "<----------NEW
NODE_FLIGHTS TYPE REF TO IF_WD_CONTEXT_NODE.
* CARRID TYPE SFLIGHT-CARRID,
* CONNID TYPE SFLIGHT-CONNID.

SELECT * FROM SFLIGHT
INTO CORRESPONDING FIELDS OF TABLE IT_FLIGHTS   "<-----------NEW
WHERE CARRID = CARRID AND
CONNID = CONNID .
NODE_FLIGHTS = WD_CONTEXT->GET_CHILD_NODE( name = 'FLIGHTS' ).

Your are using:

* get single attribute
lo_el_context->get_attribute(
EXPORTING
name = `CARRID`  "<-------------------not found.
IMPORTING
value = lv_carrid ).

* get single attribute
lo_el_context->get_attribute(
EXPORTING
name = `CONNID`
IMPORTING
value = lv_connid ).

but there is no attribute 'CARRID'.

Check your context. Maybe you didn't add CARRID to the context or you renamed it, e.g. ip_carrid or something.

You have to correct your context-attributes names => ip_carrid to carrid.

This must also be done to make "select * ... into corresponding fields of table" work.

Tip:

When creating context-nodes with attributes from DB tables/structures use right-click-menu-on the node and find "add attribute from structure" or similar. My systemlanguage is not english, so I don't know the exact spelling in english of this menu-entry.

[former_member211591]

I think you are using your context not correct.

I assume you have followig context:

CONTEXT (node)

---FLIGHTS (node) (1..n)

-

---

CARRID (attribute)

-

---

CONNID (attribute)

-

---

...

if so, this will not work. Because CARRID is no attribute of node CONTEXT ("WD_CONTEXT") but node FLIGHTS.

ONACTIONSEARCH Method

method ONACTIONSEARCH .
DATA lo_el_context TYPE REF TO if_wd_context_element.
DATA ls_context TYPE wd_this->Element_input.
DATA lv_carrid TYPE wd_this->Element_input-carrid.
DATA lv_connid TYPE wd_this->Element_input-connid.

* get element via lead selection
lo_el_context = wd_context->get_element( ).  "<-----This is not want you want to do

* get single attribute
lo_el_context->get_attribute(
EXPORTING
name = `CARRID`
IMPORTING
value = lv_carrid ).

Correct as follows. First delegate to your child node FLIGHTS before you get_attribute:

ONACTIONSEARCH Method

method ONACTIONSEARCH .
DATA lo_el_context TYPE REF TO if_wd_context_element.
DATA NODE_FLIGHTS TYPE REF TO IF_WD_CONTEXT_NODE.   <----new
DATA ls_context TYPE wd_this->Element_input.
DATA lv_carrid TYPE wd_this->Element_input-carrid.
DATA lv_connid TYPE wd_this->Element_input-connid.

*Delegate to flights
NODE_FLIGHTS = WD_CONTEXT->GET_CHILD_NODE( name = 'FLIGHTS' ).    <----new
* get element via lead selection
lo_el_context = NODE_FLIGHTS->get_element( ).    <----new

* get single attribute
lo_el_context->get_attribute(
EXPORTING
name = `CARRID`
IMPORTING
value = lv_carrid ).

Its too difficult for me to help you without seeing what you have done/are doing.

I think you have troubles with the understanding of context-navigation, and reading/setting context attributes and nodes.

I can't explain you a complete WDA tutorial here. Please refer to online tutorials or SAP help.

I am sorry that I can't give you further help.

Hi

Node Cardinality is 0...n

Selection 0...1

init..lead selection is YES

Singleton YES

Please correct me if am wrong

hi

thanks for prompt revert and patience

i will try at my end

Hi...

I guess, the structure of your context-node is not the same as the structure (SFLIGHT) of the internal table you bind to the node. (You didn't use "Add attributes from structure (SFLIGHT)", or you didn't add all fields of the structure, or you deleted the structure afterwards from the nodes properties.)

Compare these structures, and also check the order of the fields (they have to be the same too.)

Hi,

Code is right.Did you debug it.

Karthik.R

[former_member199125]

I dnt seen any error in code.. just try to pass meaning ful value..make sure you use sama data type in carrid and connid from sflights table..

and for debugging just put a breakpoint in your method,

HI Srinivas

i tried with correct values but again it showing the same error

while trying to debug the code by setting BREAK-PONT.

but while Activating the view , the cursor is not setting the specified line

can u please guide me how to debug the views with methods by step by step.

correct me if am wrong in above posts methods or required further information about my application.

Regards

Giridharan R

[former_member199125]

Giridharan,

Understand that you have put static break point in your source code..

Did you execute your application ? if yes, still debugging not take place.. It means corresponding code not executing at all.

Please try to post ur code method wise...

Regards

Srinivas

[Former Member]

Hi srinivas

methods wise in the sense ?

methods that i mentioned in 1st post is the methods which i am using in my application.

i am not able to get the track please guide me
