Update file properties of Lookup field in document library
i use the attachment control (copied outside of the form) and a dropdown field (contains metadata 'DocumentType') to upload files in a document library. I create a folder with a unique name and inside the folder i want to insert the relevant documents.
Document Type column in the Library is a lookup field. So when i reach the step Update file properties i get the DocType Id field.
How can i update the property as it is not a choice field to use the value?
