Map time-dependent InfoObject to time-independent InfoObject

Hello

we have recently made an InfoObject (0BPARTNER) time-depentent. Another Z-InfoObject is being populated by 0BPARTNER. During loading data to the Z-InfoObject (not time-dependent) we get an error (see attachment). Before 0BPARTNER has been time-depentdent it worked fine.

My question is, does the Z-InfoObject have to be time-depentdent as well?

Regards,

Florian
