If you are utilizing the company directory then you are probably building a new company directory tree every morning for the current day's use. Eventually you are going to need to delete these old trees or it will have a performance effect on your directory or your SES search index for person. This is the code from the one step Application Engine that I wrote to delete those old trees that have served their purpose. It finds the max effdt tree and then deletes any historical trees that were created three days before that date. Please note, if you are building any future dated trees, you will need to modify this code to prevent you from deleting the current effective dated tree.
&Session = %Session;
&MYTREE = &Session.GetTree();
Local Rowset &TREE = CreateRowset(Record.PSTREEDEFN);
SQLExec("SELECT MAX(EFFDT) -3 FROM PSTREEDEFN WHERE TREE_NAME = 'COMPANY_DIRECTORY'", &Max);
&count = &TREE.Fill("Where FILL.effdt < :1 and FILL.TREE_NAME = 'COMPANY_DIRECTORY'", &Max);
For &X = 1 To &count
If All(&MYTREE) Then
&RETVALUE = &MYTREE.Delete("", "", "COMPANY_DIRECTORY", &TREE(&X).PSTREEDEFN.EFFDT.Value, "");
End-If;
End-For;
