Summary

mass upload of DFF on a worker's assignment

Content

hi all.

i'm trying to use HDL in order the mass upload a DFF managed on a worker assignment.
i would appreciate your help in guiding me of the right syntax the first metadata row should have.

i understand the metadata should have two columns, one for the context and the other for the values.
the name of my DFF is "professionaility". i have added a screenshot taken from the "worker" business object mapping that might assist.

thanks for all the helpers.
Ben.
