__EMPTY_SELECTION__ Lock Integrated Planning

Hi all.

I'm running an input-ready query through a InfoCube. Actual for Plant and Calmonth.

So far so good. I managed to get the query input ready and it saves back to the cube alright. I haven't used any planning functions or filters within IP - just created a aggregation level on the InfoCube and the wrote the query on top of that.

Next problem is that I'm trying to manage the locking conflicts. I will probably have 10 or more people that possibly could be running this query at the same time (who are all responsible for different Plant). So I figured I could set Plant as the lock characteristic on my planning cube, because we will only have 1 person filling in numbers for each Plant.

After a lot of trial and error I get this __EMPTY_SELECTION__ as a locking reason. I can't get this to work.

I'm using Plant, Material, Calmonth in my query. Along with Amount as key figure.

I have tried alternating the lock characteristics to different ones, but with no luck.

Maybe, I need to use in my query, the variable in plant.

Please help.

    Hi Karim,

    __EMPTY_SELECTION__ indicates that the selection table used for the enqueue request is empty, i.e. this lock request locks the whole cube. As a result this lock overlaps with all other enqueue requests for this real-time InfoCube.

    What to do:

    1 If 'Plant' is the only lock relevant characteristic, maintain 'Plant' in as lock relevant in transaction RSPLSE, i.e. 'Plant' is contained in the 'right hand' table (the lock relevant characteristics) on the second tab. Observe, that the default is that all InfoCube characteristics are lock relevant, i.e. contained in the right hand table. Maybe you made all characteristics except 'Plant' lock relevant.

    2. In the filter of the input-ready query use the restrictions for 'Plant', e.g. a single value. You may use a variable for this. It is important that the restriction is in the filter, not in the default values. The query filter used to set the locks.

    3. The same is true for planning functions.

    Using this modeling you will get no lock conflicts.
