How To Fix RU493 - Invalid entry: Job repetition can lead to infinite loop

RU493 - Overview

• Message type: E = Error

• Message class: RU - Messages for order completion confirmation

• Message number: 493

• Message text: Invalid entry: Job repetition can lead to infinite loop

What causes this issue?

You have entered a value for "Maximum number of goods movements
selected" and activated the indicators "With incorrect goods movements"
and "Repeat job". This setting can lead to an infinite loop and is thus
not permitted by the system.

System Response

If the value Y is entered for the selection parameter "Maximum number
of selected goods movements" then Y values are read in from the table
AFFW (table for goods movements in background and incorrect goods
movements). If the report is carried out with incorrect goods movements
then it is possible that the report has selected Y incorrect AFFW
records that again lead to an error.
If the report is called up again then it would select the same values
again. Processing the AFFW table is thus not possible and results in an
infinite loop.

How to fix this error?

If you want to carry out a report "Maximum number of selected goods
"movements" the you should deactivate either "Repeat job" or "With
incorrect goods movements".

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