Brian, I think the start of that section is: <PDM_MACRO name=startNotebook hdr=prro_nb>
So, move:
<PDM_MACRO name=startTabGroup title="Parent/Child_Relationships">
<PDM_MACRO name=tab title="Attached Incidents" height=300 id=att_inc src="OP=SEARCH+FACTORY=in+QBE.EQ.problem.id=$dob.id+KEEP.forPRtoIN=1+KEEP.PR_PERSID=$args.persistent_id+KEEP.PR_ID=$args.id+KEEP.PR_REFNUM=$args.ref_num">
<PDM_MACRO name=tab title="Parent/Child" file="pr_relreq_tab.htmpl" id=rel>
To just after:
<PDM_MACRO name=startNotebook hdr=prro_nb>
