HI,
data loading time and index creation time locking happening.
data loading using ssis packgage we have created ssis packges based on ONCE COMPLETION OF LOADING THE TABLE(completion line) THEN only PRCOCESS Should go to the NEXT container.this is the way of the Exettion of data loaidng .in the case of indexes we have created Stored procedures.each procedure have 3to 4 index.in this case also same once completion of the Stored procedure(Execute Sql task) then only shold to the next Execute sql task.

why not add the index creation as a different step altogether in sql job and remove it from current package?
