CA-TS-PS and message LR265 - Unit not permitted

Hello,

Please help me with the following: I defined several activity types for equipments, in use by our groundworkers. The idea is to use CAT2 for entering the activities and transfer this activities to network activities. The activity types are defined with KL01 and planned on the sender Cost center with KP26.

The time sheet layout is customized for entering different activity types, the working place (PS) maintained in units. We don't want to use the unit "hours" or any other timebased unit.

So far, so good. Transferring these activities to internal orders, wbs elements or cost centers works well.

But entering the same activity types in combination with an network activity results in Error message "LR265 - Unit not permitted" from CATS_CHECK_INPUT.

Is there a way to avoid this error message?

Kind regards,

Diana
