Import set rest api runs all the associated transform maps but not only the specified one

[zhanglixin]

1. when I create a import set rest api, I specify a transform map. For my understanding, the rest api should only run the specified transform map. 

2.But confirming the  running result, it seems that  it runs all the two transform maps. I don't know why.

I dont think you can pass the transform map in the request api. You need to have a onStart or onBefore script to ignore the import using the other transform map based on data coming via the import set api.

Discussion in below thread should help.

SanjivMeher, Thank you for replying.
If the import set rest api will run all the transform maps anyway, I don't understand the intention why we can specify one transform map in the parameter.
