How to Inject mrvs to data?

[110100]

Hello Community,

I would like to put the value to 'mrvs 'post_transfer_request_variable_set (sysid: d1f902b31bbc42d0f078a60ce54bcb12)'.
However, it returns a result of 'test_multi_row []'.
I am using 'test_multi_row(MultiLine)' now as a test, what improvements are needed to put the value into 'post_transfer_request_variable_set(MRVS)'?
