Destination "APT_TRinput0Rec0" is already bound

[rachit82]

I am doing 2 lookups in the following fashion:

1) Lookup if record is found or not.
a) if found go to lookup 2.
b) if not found then go to transformer where a column status is set and then to dataset.

2) Lookup to see if all the column values in stream match the lookup dataset.
a) If found then to transfomer, set status and then to dataset.
b) If not found then to transformer, set status to dataset.

there were not errors on compilation but then i run the job, the only error message i get is:

main_program: Fatal Error: Destination "APT_TRinput0Rec0.ITDEF1" is already bound.

Please advise.
