update in RFCDES

[hannover_sap-basis]

Hello,

in the document "SAP System Landscape Copy for SAP NetWeaver and SAP Solutions" [https://websmp102.sap-ag.de/~sapidb/011000358700003128302006E] i can read

Disable system connections / RFC destinations to prevent any communication from being issued by the system. Execute an SQL statement which invalidates the hostnames, respectively the IP address in the main RFC connections table, for example by adding a suffix u2018.copyu2019 or a prefix u2018#u2019 to the hostname / IP address. The hostname / IP address is contained in field RFCOPTIONS of table RFCDES. This step can help to prevent any messages from being transferred from the target to the source environment. The actual adjustment of the destinations to their final values (the real servers of the target environment) is done later in step 6.4 using the official SAP transaction SM59.

Do you have any code examples code to update the table RFCDES.

Better approach is to export the table from the target system and then import it back in after the copy. this will prevent the problem from occuring.
