Hi Vijaya Kumar,
Thank you.. I think I am almost near..
In the issue colomn...(Vendor Number) on top it is showing dynamic coloumn..
I had a look into SWL1,
Task Expresssion Header
TASK1 &_WI_OBJECT_ID.VENDOR& Vendor Number
TASK2 &LIV.VENDORNUMBER& Vendor Number
TASK3 &LIV.VENDORNUMBER& Vendor Number
TASK4 &DYNAMICCOLUMN4& Invoice Amount
Task 4 is full of dynamic coloumns and in the task4 &DYNAMICCOLUMN2& is vendor number.
But task 3 is the issue task pointed out.
B.R.
