The user is able to view the signature after the account signs in from the Sign In sheet of a Medical Event on CRM iPad. The Clear button displays for that record before syncing.
The user is unable to view the signature again from a Sign In sheet of a Medical Event after syncing on CRM iPad. The Clear button disappears.
The VMobile Object Configuration (VMOC) of Event_Attendee_vod has Signature_vod__c on the Exclude_Field_List_vod. It is expected that the signature is not visible on CRM iPad after syncing and the Clear button disappears.
As per the online guide: Event Attendee Signature Capture, it is suggested that the Exclude_Field_List_vod field on the VMobile Object Configuration record for Event_Attendee_vod should contain the following value of Signature_vod__c.
We exclude the Signature_vod__c field because it is an image file and it consumes significant bandwidth and storage to sync all the signatures down to CRM iPad.
This is currently working as designed. The VMOC excludes the signature for bandwidth and storage reasons. The user still can see the signature by removing Signature_vod__c from the Exclude_Field_List_vod of VMOC of Event_Attendee_vod. Note: Be aware of the downside.
