ABAP Debugger - modify values

[Former Member]

Hi,

In the new ABAP debugger when you double click on a variable there is a little pencil icon to the change the content of the variable. If the variable has more than 255 characters or if you chnage the variable to a long text of more than 255 then it says only the first 255 characters will be transfered.

I wanted to know of there is a way to change longer texts than 255.

Thanks.

If your string is e.g. 400 characters long you can use

lv_string+255(145) to change the characters after 255. It's a bit clumsy, but it works.

Hi,

So you mean i type lv_image+255 in the debugger variable column.

I tried it and it doesnt recognise it lv_image any more.

Yes, but you also have to specify the length you want to display.

variable+offset(length)

Only then you can change the value.

Hi Michael,

I think your solution will work only if its the technical type is char, in my case he technical type is cString and if i try the offset it doesnt work. when i clicked on the message it gave me this.

If changes are made to LV_HTML, only the first 255 units are transferred

Diagnosis

You tried to change a variable value that is longer than 255 bytes or characters.

Only 255 elements of the value of a variable are passed between the Debugger and the debugged development object.

Therefore, you cannot change more than 255 elements of a variable value when changing a variable.

The remaining elements are set to the initial value, in the case of characters and X fields, or shortened to a length of 255 characters/bytes, in the case of strings and XSTRINGS.

Procedure

To change parts of a long Char field, you can use offset and length specifications.

Example:

To change the first character of a Char(1000) field C1000, use the variable name C10000(1) and change it in the variable fast display.+

Unfortunately, there is no solution for strings and XSTRINGS yet.

I guess in mycase there is no solution.

Thanks.
