It depends a bit how the SP01 Spool entries looks like to select the right once related to the BW Process Chain and maybe it's Sub Chains. To have a look in SP01 is strongly recommended before starting with definition and design. With the R3_GET_SPOOLREQUESTS capability of Automic (aka UC4) you can select the spools created with one or multiple jobs require. Please store this information in a Variables Object. Next Job is doing now the R3_GET_JOBSPOOL with the information already stored in the Variables Object. To download the spool.
