    Create two contexts to resolve the chasm trap:

    C1: Property, Calendar, Department, Ledger

    C2: Property, Store, Zone, Ledger1

      Hi Abhi,

      You don't need to create alias for ledger table just create an alias for property table and then join the same with ledger table on 'Property_ID' column.

      remining join will be like

      Ledger table is in center & all the tables like Account,Store,Zone,Calendar,Department,Property & alias of property will join to Ledger table.

      I hope this will help you.

    Hi Abhi,

    Traps occurs on universe when there is one to many or many to many or many to one cardinalities present between the tables.

    Basically two types of traps can occur on universe you might know about it.

    If not refer the link

    Business Objects: Chasm Trap

    Business Objects: Fan Trap

    now to avoid this you can go to universe parameters there you will find an option called "Multiple SQL for each measure" option.

    Please provide your report output where you feel that trap is occurring.

    That will help us to understand the problem.

    Thanks,

    Swapnil

    Delete all your existing contexts and click on the detect contexts button. Accept all suggested contexts. Done. It's one of the best features of the UDT that if you have your cardinalities set correctly for all your joins, then context detection works a treat. It's worked in the same way since I started using it on the old version 4 on Windows 95.
