Conversion of type "g" to type "h" not supported.

[Former Member]

Hi friends,

In select-options component, while assigning the Range table Value of the select-options field( PERNR ),

to exporting parameter VALUE of the SET_ATTRIBUTE method,I am getting the error as

Conversion of type "g" to type "h" not supported.,

kindly, provide me some inputs, in solving this Issue.

Regards,

Hi,

Try giving the Range table value as 'PERNR_D' instead of 'PERNR'. I faced the same problem before and it got resolved because of the below changes.

example:

wd_this->m_handler->create_range_table(

i_typename = 'PERNR_D' ).

• add a new field to the selection

wd_this->m_handler->add_selection_field(

i_id = 'PERNR_D'

it_result = lt_range_table

i_read_only = read_only ).

Thanks,

Hi Raj,

Below is my Code, Before pernr, I am able to set the value of Begda to set_attribute, but when I am trying to set the Pernr values to set_attibute method, the above Error occurs.

I think you might have a type ref to data that you are trying to pass into the interface parameter, but it is difficult to tell from your code fragement because not all the data declarations are there. What is the data type of L_SEARCHPARAMETER-VALUE?

L_SEARCHPARAMETER is of type IHTTPNVP.

Hi Xavier,

I'm not sure wether this will work for you. I applied the same to avoid the error.

Please give it a try.

Regarding fieldsymbols assignment and moving it to another variable.

field-symbols: <fs> type data.
data lt_final type standard table of WDR_CONTEXT_CHANGE.
data ls_final type WDR_CONTEXT_CHANGE.
data ls_flights type ref to wd_this->element_flights.
data lv_var type string.

 read table lt_final into ls_final index 1.

case ls_final-ATTRIBUTE_NAME.
when 'CARRID'.
        assign ls_final-new_value->* to <fs>.
          lv_var = cl_wdr_conversion_utils=>to_string( value = <fs> ).
       ls_flights-carrid = lv_var.

when...

Endcase.

Try to understand this piece of code and apply the same where ever neccessary.

I think cl_wdr_conversion_utils=>to_string( value = <fs>) is the statement required to avoid conversion errors which you got.

I think you are directly assigning the fieldsymbol to the variable. This would be the possible cause of the error.

L_SEARCHPARAMETER-VALUE = L_STRING. 

ASSIGN L_SEARCHPARAMETER-NAME TO <FS1>.
ASSIGN L_SEARCHPARAMETER-VALUE TO <FS2>.
*<FS1> = L_SEARCHPARAMETER-NAME.
IMPORTING_NODE->set_attribute(
exporting
name = <FS1>
value = <FS2> ).

Try to move the <FS1> to other variable of type string then move it to the name ans value attibutes of the methods.

Have a look at the usage of this class cl_wdr_conversion_utils.

Lekha.

Hi Lekha,

What is the Method that is used for converting field-symnbol data to DATA format?

Becuase in set_attribute method parameter 'value' is of type DATA.

Xavier

[Former Member · Accepted solution]

Hi Xavier,

Please try to use the conversion class as specified above because in some cases we cannot directly move the fieldsymols to variables. We need to convert them to the target variable type then we can move to the actual variable. Please try to understand my code snippet in earlier post.

Regards,

Lekha.

Hi Xavier,

Please check out with the fieldsymbols you are using to populate the range table.

Check the structure of the Range table you are trying to populate.

I think the VALUE is of DATA type, it means a fieldsymbol.

Lekha.
