Error determining planning periods for calendar 007 (message no. 61123)

Hello Friends,

While using the planning calendar for planning of raw material, i am getting the error message " error determining planning periods for calendar 007 (message no. 61123).

Diagnosis:The system couldn't determine sufficient planning periods by the planning calendar to group reqmts by planning calendar periods for all the requirements planned the future.

I have maintained the following settings.

I have kept MRP Type for Raw material as PD and lot sizing procedure as PK and have maintained planning calendar 007in MRP 2 View of Raw material , material master.

While creating the planning calendar 007,i have selected the calculation rule as Weeks (week days) and valid from 04.09.2008 and Valid To 10.12.2008.With this i have maintained Thursday as Period begin on the following week days.

Now when i check the periods it shows following periods


From date Period To Week

04.09.2008 10.09.2008

11.09.2008 17.09.2008

18.09.2008 24.09.2008

and so on upto 10.12.2008

Now i have given planned independent reqmt of finished material on 23.09.2008 of 20 qty, 26.09.08 of 20 qty and 29.09.08 of qty 20

Since i have defined the suitable periods than also system is giving me above error.

Help me in finding the problem.Thanking you.
