My initial requirement is to have column level permission in a custom list.(Set of users can see the column and set users cannot).
Since SharePoint doesn't support column level permission i have tried to use a workaround with two custom lists. One with the specified column ie:CusList_A and another without the column ie:CusList_B.
Then i created a workflow for CusList_A. I designed the workflow in a away that, when a new item is added to the CusList_A the workflow will create a new item in CusList_B with the values of CusList_A.
The problem is that CusList_A have a coulmn for an attachment. Standard settings of the workflow doesn't allow me to get the attachment from CusList_A and to set it as the attachment of CusList_B.
How can i get an attachment from one custom list and to put it in another custom list using a workflow?
