SQ01 and SE93

Trying to add a bespoke transaction code to a query I have created via SQ01. I ran the query and got the code behind it from System->Status. I then added the program name and screen 1000 to the transaction. The quesry and the transaction were then transaported into the QAS box. When I run the transaction in QAS I get a run time error where it says a field-symbol has not been assigned. The field-symbol is assigned in the initialisation block of the program. Have I done something wrong when assigning the query to the transaction code as when I run the query in QAS vie SQ01 all runs fine.
