MODULE STATUS_0500 OUTPUT.

• SET PF-STATUS 'xxxxxxxx'.

• SET TITLEBAR 'xxx'.

CASE OK_CODE.

WHEN 'ADD'.

IO3 = IO1 + IO2.

WHEN 'SUB'.

IO3 = IO1 - IO2.

WHEN 'MUL'.

IO3 = IO1 + IO2.

WHEN 'DIV'.

IO3 = IO1 + IO2.

WHEN 'EXIT'.

EXIT.

ENDCASE.

ENDMODULE.

my tranjection name is- zgytest,

and when i m trying to execute it, it is giving message like- Transaction contains inconsistencies. Do you

want to execute it anyway?

IF I M EXECUTING IT, and debugging it,, in the io1 and io2 variable, i m getting value, but when cursor is coming to

check OK_CODE, its not checking and hence result is not getting printed in i03 box,

so can any one tell what is the solution for this plz,
