Can't copy data from Infocube to planning area

Dear SAP expert!

When I copy data from infocube to Planning Area, there is massage as below. Then I can't copy data any more

No data exists for the selection made (see long text)

Message no. /SAPAPO/MA401

Diagnosis

Data could not be loaded from the Cube for the selection you made. Check whether the Cube actually contains data that is relevant for your selection.

If data does exist, check that all the time characteristics of the Cube are filled. If not, the program does not return data since it always uses all the time characteristics of the Cube when making selections.

Procedure

If the problem is caused by unfilled time characteristics,

you have to fill them or remove them from the Cube. Procedure for System Administration

I hope to see your help soon

Tks,
