No syntax errors found

What causes this issue?

You have chosen 'syntax check' while implementing SAP Notes with the
Note Assistant.

System Response

The system has checked whether the programs changed by way of this SAP
Note implementation are still syntactically correct at the end of the
implementation.
No syntax errors were found.
However, note the following special case:
For technical reasons, the system is currently unable to check global
classes or their subobjects, such as methods (object type METH). As a
result, any syntax errors in one of the classes affected by the SAP Note
implementation are not identified.

How to fix this error?

If methods are changed by an SAP Note, we recommend that you check the
affected programs again after the SAP Note has been implemented.
This is an option in the Transport Organizer, for example: have the
system display the change request in which you recorded the SAP Note
implementation. From the Request/Task menu, choose 'Overall Check' ->
'Objects (Syntax Check)'.
If syntax errors are found, you can also cancel the SAP Note
implementation at this moment.
