What causes this issue?

This utility analyzes ABAP/4 program source code. The program analysis
can analyze programs with incorrect syntax, provided the errors are not
too serious (e.g. undefined fields in a statement). An example of a
serious syntax error would be a missing quotation mark, since this can
result in a literal which is too long.

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?

Perform a syntax check on the program which caused the problems. When
you have corrected the program, you can use the <LS>Refresh index</>
function in the ABAP/4 program editor (see <LS>Utilities</> menu) to
resume the action that was terminated for this program due to errors.
