We are using IFS 9 update 14 with multi-company connections.
A user from our US company is trying to register project time for a connected project/activity from our Finnish company. When saving the entry they get the error message: You cannot modify project transactions of company CCUS without a valid position assignment.
The users have been setup as multi-company correctly and have successfully registered time for other multi-company projects. We have seen this error occur for another muti-company project. The solution for that issue was a missing default site value on the project. (Not the solution this time.)
We assume there is an issue with the project/activity or multi-company connection but, the time reg. message is not providing much help. Comparing the problem project with another working project has not shown any differences in the configuration.
