Hi Everyone,

I have a data list with two columns (A and B), containing numeric values. I want to automatically add the values of column A to colum B for MULTIPLE data items. I want to do this with a workflow, however, so far I have only been able to execute the workflow for one data item, while I would like to automatically execute the workflow for multiple items in the data list at once. Is there an (easy) way to do this?

Nick

If you only need to add two fields together, the most efficient way is to use a computed column. If both columns A and B need to be modified, it is recommended to add column C to sum the values of A and B. If only column A needs to be modified, you can directly change column B to a computed column. (Please note, this requires two steps: first, add column B and keep the expression empty. The second step is to modify the expression of column B.)
