How To Fix TPDA068 - If changes are made, only &1 units are transferred per component

SAP Error Message - Details

• Message type: E = Error

• Message class: TPDA - Debugger

• Message number: 068

• Message text: If changes are made, only &1 units are transferred per component

What causes this issue?

You tried to change a variable value that is longer than &V1& bytes or
characters.
In the variable fast display, structure-, object-, and table view, only
&V1& elements (bytes for type X fields and XSTRINGs, and characters for
character-type fields and strings) for each variable value are passed
from the debugged development object to the Debugger.
Therefore, when changing variables, note that only these &V1& elements
of a variable value are passed from the Debugger back to the debugged
development object.
The remaining elements are set to the initial value, in the case of
characters and X fields, or shortened to a length of &V1&
characters/bytes, in the case of strings and XSTRINGS.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

System Response

How to fix this error?

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 C1000+0(1) and change it in the variable fast display.
Unfortunately, there is no solution for strings and XSTRINGS yet.
