I get the below error while trying to set same target field (Virtual) in 2 different target tables under the same transform map.
Error - "An existing map to this target field already exist"
My requirement is to set the target field "Is Virtual(virtual)" for 2 target tables in the same map. Below are the 2 target tables am trying to map the field to
cmdb_ci_lb
cmdb_ci_netgear
Solved! Go to Solution.

you have only 1 transform map and you want to set 2 target fields with same source value?
If yes then system is blocking you?
If yes then why not use onBefore transform script for the 2nd field like this
target.fieldName = source.u_is_virtual;
If my response helped please mark it correct and close the thread so that it benefits future readers.

Hi @Gautam Raj ,
Can you share the screen shot of your transform map where you are getting the error?
Regards,
Rohit

Hi @Gautam Raj ,
navigate to sys_transform_entry.LIST and check if you've any similar record (same map,same target field)
FYI: Ensure unique target field this BR is aborting the action
if no duplicate records found , rename u_virtual name
