String parameter problem

[Former Member]

Hello,

I get a strange error when calling a method with

a parameter of type String. With debug the varaible use

as parameter has the correct value, using explicit value

the method its work.

Here some code for a better understanding:

This way is not working

<i>

Call Method g_tree->add_node

Exporting node_key = l_tm_child

<b>relative_node_key = l_tm_parent</b>

relationship = cl_simple_tree_model=>relat_last_child

isfolder = ' '

text = l_child_text.</i>

where l_tm_parametr is of type String and has value 'BMECAT'

But with expicit value will work :

Exporting node_key = l_tm_child

<b>relative_node_key = 'BMECAT'</b>

relationship = cl_simple_tree_model=>relat_last_child

isfolder = ' '

text = l_child_text.</i>

Anyone knows what's the problem?

I've met this problem once more when comparing String?

Many Thanks!

Hello,

don't understand your problem ... but I declare relative_node_key as type lvc_nkey.

maybe that will help you

Hi Bogdan,

The parameter for the method is of type TV_NODEKEY which is a Character field of 12 positions. You can't use type string for this.

Kind regards,

John.

Hello John,

The type for parameter relative_node_key is TM_NODEKEY which data type is STRING ( in method cl_simple_tree_model->add_node).But thank you anyway

One thing that I notice at debug is the hex value differs

for 'BMECAT1' is <b>424D4543415431</b>

and for varible l_tm_parent is <b>424D454341543120</b>.

Another thing to say is that before calling method I make

a concatenation between 'BMECAT' and 1 into l_tm_parent.

( actually the value is BMECAT1 ).

Thank you!

Bogdan

ps. sorry for my english

Hi,

I figure the cause of the error

using concatenate on 'BMECAT' and an integer, an extra character is added at the end of the string

But If the integer is converteted to N (numeric chars)

the concatenate works fine.

Thank you!
