I came across an issue related to adding Multiple Selection option for a new field to an existing form in a VC model. When adding the new field, only option I was getting was single value selection.Value help configuration wizard was not showing option for Multiple value selections. In this blog I’m explaining the issue and sharing the procedure I followed to overcome it. There are many helpful SDN posts – listed below, on the same issue.
In data flow below, requirement was to add more selections fields on the Form “Selection Screen” with value help showing option for multiple value selection.
Existing data flow.
When I added new fields to the selection screen form and then adding value help to it, I was always getting option only for single value selection. Type drop down box didn’t give option for multiple value selections.
Steps followed to overcome above said issue:
1. Delete the connection & selection screen form connected to the input of query.
2. Add new form by clicking on input port of the query to which you have to pass variable value and add all the required field for selection in the new form.
(So that this new form will be copy of deleted in step 1 with additional fields).
3. Right click and add Value help to individual fields.
4. Now you will be able to see Multiple select option on that field.
Rest of the process is same as you would follow to add value help.
