An implicit conversion is being performed from a value of type '{0}' to a value of type '{1}'. This conversion can lead to data loss and unexpected runtime issues.
How to fix this diagnostic?
This warning means AL automatically converts a value from one type to another, and the conversion could truncate data or lose precision. Typical cases are assigning a longer text to a shorter Text or Code, or narrowing a numeric type.
To fix it, make the conversion explicit and control the length or precision. The following example can lose data because the text can be longer than the target:
CodeValue := TextValue;
Use CopyStr to control the length:
CodeValue := CopyStr(TextValue, 1, MaxStrLen(CodeValue));
