Execute Parallel Read for Delta <#nnn>
Step type: Simple user interface.
Step description: This step builds the parallel read partitions for the generated <#nnn> delta run, where <#nnn> is the number that represents the order of the delta run. The parallel read is built based on the data collected in the trigger shadow table since the previous delta run or since the activation of triggers when <#nnn> = 001 (the parallelization is set for the first delta run). For more information, see the chapter DTS NZD Processing.
