Hi Experts!

Can anyone tell me, what means error: "Type conversion is not possible because 1 of the operators contains an invalid type. Integer t_testcase VOID"

    Can you active debug and post the code that generates the error?
    it would be helpful

    This generally happens when you perform GET on a table, which has a combined primary key, with incorrect key order. Turn the debugger on and find out where it happens.

    Quick scenario:
    There is a table with primary keys Code and Integer Type.
    If you perform a GET(10,’US’) instead GET(‘US’,10), this is the error message you would receive.

    So, trust the debugger and change the field order in GET.

    Another possibility is that you have named some function or variable as some field or another variable - it means check the naming in the line, where the error is called.

    "t_testcase" points to a problem with a CASE statement. The VOID generally indicates that you are attempting to use the result of a function (probably a user defined function) that does not return a result.

    ok,

    the problem may happen in CASE OF when you don't use BEGIN END statements.

    CASE Index OF

    1:
    x := x + 1

    2:
    x := x + 2

    3:
    x := x + 1;
    a := a +1;

    4:
    a := a +1


    on the third case, you recieve t_testcase void error. check begin and end statements.

    Thank you very much! The problem happened in CASE OF. Now it works.
