I'm not certain why we are calling the script include and querying the dictionary at all as we already know the tables because they are being used to generate the query. If the intent is that I don't know what table my id is for so I want it to try multiple tables then you can do something like the following untested script:
var tables = ['kb_category','kb_knowledge_base'];
var id = "25cd15c3ac6c728056e1781325626541";
for (var i = 0; i < tables.length; i++) {
var gr = new GlideRecord(tables[i]);
if (gr.get(id)) {
target.parent_table = tables[i];
target.parent_id = id;
break;
}
}
But if you know the table, it should be as simple as:
target.parent_table = "kb_knowledge_base";
target.parent_id = "25cd15c3ac6c728056e1781325626541";
In either case, I would remove the field mapping entries in favor of the on before script to guarantee ordering.
