Records on the Related List of an Object do not display offline when they display online. The record downloads to the device based on the Vmobile Object Configuration (VMOC) but does not display.
The records display all related items unless the related list contains an Autonumber field as a displaying column. The record must have a valid reference to display offline. The standard SFDC Name name field is either a Autonumber or Text(80) field.
For example, if a Contract Partner related list on the Account page has the Call field displaying as a column:
- Contract Partners with either no Call associated or a Call that is syncing to the device display.
- Contract Partners with a Call associated that is NOT syncing to the device do NOT display.
Check the Related List fields on the page layout the record is for to see if there are any Autonumber fields and make sure all referenced records sync down the device.
