Just created a new Gen Client Server Encyclopedia (CSE) and when attempting to upload an existing model receive the following errors:
MDLADPT:
Function Work Attr Set TIMESTAMPDATETIME could not be found in table
MDLADPT:
FUNCDEF TIMESTAMPDATETIME could not be found in table
Release : 8.6
Gen Client Server Encyclopedia (CSE)
The timestampdatetime function was first added in Gen 8.6 IR1 (Windows PTF IRN86100/RS94237) and is also in Gen 8.6 Complete (Windows PTF WKS86200/SO09618)
Gen™ 8.6 > Release Notes > Gen 8.6 GA Complete (8.6.2) > Incremental Release 1
From the message it would appear that the model being uploaded already contains the new timestampdatetime function i.e. it is at a post Gen 8.6 IR1 release level, but the new CSE is not aware of the function because it is not yet at that release level.
Installed the Windows PTF for Gen 8.6 Complete WKS86200/SO09618 on the new CSE to resolve the problem.
