How To Fix SY373 - Error number &1 receiving the results of an OLE call

SAP Error Message - Details

• Message type: E = Error

• Message class: SY - ABAP/4 system messages

• Message number: 373

• Message text: Error number &1 receiving the results of an OLE call

What causes this issue?

The system could not assign the results of an OLE Automation call to
the correct program variables.
Meanings of the error number <(>&<)>1:
-1: The event memory of the automation queue is destroyed - internal
error
1: There is no valid link to the program variables (PcbInvalidId)
2: The link cannot be expanded (PcbInternal)
3: The link points to an internal table that has been cleared
(PcbItabFreed)
4: The link points to a local variable whose stack frame has been
released (PcbStackFreed).
Note: Errors 3 and 4 indicate a programming error. When you program
with controls, you must ensure that the return value (for example, the
selected node of a tree) is not written into a local variable. For
performance reasons, control calls are not necessarily sent to the
front end imnmediately, but are placed in a queue instead. The queue
may be sent to the frontend at a point where the local variable no
longer exists because, for example, the call occurred in a subroutine
that had ended by the time the queue was flushed. Avoid control calls
with local importing parameters.

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

System Response

The system assumes that correct processing is no longer possible
without the return value. To be on the safe side, it stops processing.

How to fix this error?

Depending on the kind of error, the application program may need
correcting (error number 3 or 4) or a system error occurred while
processing the automation queue (SAP Automation Controller).
