HI ,

In the event handler for ON_OVS event, there is a paramater named OVS_CALLBACK_OBJECT.

This is of type IF_WD_OVS.

Check this interface..There is a attribute named CONTEXT_ATTRIBUTE which will have the value of the Context Attribute binded to the input field on which F4 was pressed.

So put a conditional statement in the phase2 of OVS before populating table lt_select_list.

Somthing like this.

if ovs_callback_object->CONTEXT_ATTRIBUTE CS 'ATTRIBUTE1'.
           select att1 from tab into TABLE lt_select_list.
      ELSEIF ovs_callback_object->CONTEXT_ATTRIBUTE CS 'ATTRIBUTE2'.
          select att2 from tab into TABLE lt_select_list.
      endif.

should work.

Thanks,

Aditya.

Hi Aditya,

Thanks for ur replay.

Here you have written the correct logic to call the correct query based on Field Selected.

You need to write the same logic while passing data back to your input field.

Inserting the blow statement , will correct your problem.

if ovs_callback_object->CONTEXT_ATTRIBUTE CS 'ZZNMVGR5'.

Hope it helps.

HI ,

I guess in the last phase again you need to check which node(or rather attribute) is in question and bind the values according to that.

A conditional statement similar to phase2 is needed.

Thanks.,

Aditya.

Hi All,

Thanks for ur replay ,

Once again same problem 2nd input fields is showing me balnk up to phase1 it is working fine. after that values are not getting.

can u people help me out .

thanks ,

Madhan

[ashish_shah · Accepted solution]

Did you write code that i suggested in Phase 3?

Can you explain what is Exactly happening?

[Former Member · Accepted solution]

hi ,

I used same code as u mention , for 1st input field every thing is fine.Bu for the 2nd input field upto selection it is working fine after selecting the specific one and clicking on ok data is not coming.

why it is happening lyk that.

Hi Madhan,

Put a breakpoint in the 'if' condition of Phase3 and check the value in <ls_selection>.

Also check the column names of ls_selection and check if you have used the proper column.

And also..please post your complete code once .

Thanks,

Aditya.

Hi,

Can you do this test case. 1st try to select a value in 2nd input field...

then check for 1st input field. check wether you are getting the 2nd field's description up on 1st field selection.

As you have selected the value for 2nd field right.

If the ls_selection is assigned, try to unassign this field symbol at last and test it.

Lekha.

hi all,

thanks for ur replies,

i found the bug why it is going to dump.but iam unable slove it. in phase 3 selection having a problem here i am attaching code can any one slove it .When i am selecting 2nd input it is going to 1st assinged one

assign ovs_callback_object->selection->* to <ls_selection>.

here is my code

when if_wd_ovs=>co_phase_3.

• when if_wd_ovs=>co_phase_3.

if ovs_callback_object->selection is not bound.

• TODO exception handling

endif.

assign ovs_callback_object->selection->* to <ls_selection>.

if <ls_selection> is assigned.

if ovs_callback_object->CONTEXT_ATTRIBUTE CS 'ZZNMVGR5'.

ovs_callback_object->context_element->set_attribute(

name = `ZZNMVGR5`

value = <ls_selection>-zznmvgr5 ).

ovs_callback_object->context_element->set_attribute(

name = `TV_PRODUCTVODE`

value = <ls_selection>-TV_PRODUCTVODE ).

endif.

endif.

if ovs_callback_object->selection is not bound.

• TODO exception handling

endif.

assign ovs_callback_object->selection->* to <ls_selection1>.

if <ls_selection1> is assigned.

if ovs_callback_object->CONTEXT_ATTRIBUTE CS 'ZZNKDGRP'.

*

ovs_callback_object->context_element->set_attribute(

name = `ZZNKDGRP`

value = <ls_selection1>-ZZNKDGRP ).

ovs_callback_object->context_element->set_attribute(

name = `TV_CUSTGRP`

value = <ls_selection1>-TV_CUSTGRP ).

endif.

ENDIF.

Hi,

You need to understand what is your mistake in the code.

You are writing same code at two places without checking the proper conditions.

Following is the correct code:

when if_wd_ovs=>co_phase_3.

assign ovs_callback_object->selection->* to <ls_selection>.

if <ls_selection> is assigned.

if ovs_callback_object->CONTEXT_ATTRIBUTE CS 'ZZNMVGR5'.

ovs_callback_object->context_element->set_attribute(
name = `ZZNMVGR5`
value = <ls_selection>-zznmvgr5 ).

elseifovs_callback_object->CONTEXT_ATTRIBUTE CS 'ZZNKDGRP'.

ovs_callback_object->context_element->set_attribute(
name = `TV_PRODUCTVODE`
value = <ls_selection>-TV_PRODUCTVODE ).

endif.

endif.

This should solve your problem.
