SAP Error Message - Details

• Message type: E = Error

• Message class: TW - R3trans - Messages

• Message number: 702

• Message text: Internal error for twrtab call: Table cache too small for view &1

What causes this issue?

To import view contents, it is necessary to compare the database
contents of the transported key area with the data to be imported. This
comparison can only take place in the main memory of R3trans.
In your case, R3trans has detected insufficient memory. Error handling
is included for this case. It is supposed to prevent the internal
function twrtab of R3trans being called with option "RT_MODIFY",
"RT_UPDATE" or "RT_INSERT", since these functions are no longer
possible.
A case was overlooked in error handling.

System Response

The entire import terminates with a "PANIC" message.

How to fix this error?

Report the error to SAP. If possible, attach the log in which the error
occurred (at least the first 40 and last 20 lines) to the message.
