Using PL/SQL to call IFS APIs

IFS is an ERP system built by the Swedish software firm Industrial and Financial Systems AB. It exposes most of its functionality for automation, customization, etc. Below is an example of how we can use a quick script (to be executed by tools such as SQL*Plus) to automate the batch creation of detail lines in a Customer Order. Many of the other exposed APIs offered by IFS can be called in a similar manner.

	info_	varchar2(4000) := '';
	attr_	varchar2(4000) := '';
	objid_	varchar2(2000) := '';
	objversion_	varchar2(2000) := '';

	cursor recs_ is
	select order_no, cust_id, part_no, qty, unit_cost 
	from my_tmp_worklist_tab;
	for rec_ in recs_ loop
		info_ := '';
		objid_ := '';
		objversion_ := '';

		-- Add attributes to the Customer Order detail line
		Client_Sys.Add_To_Attr('ORDER_NO', rec_.order_no, attr_);
		Client_Sys.Add_To_Attr('DELIVER_TO_CUSTOMER_NO', rec_.cust_id, attr_);
		Client_Sys.Add_To_Attr('CATALOG_NO', rec_.part_no, attr_);
		Client_Sys.Add_To_Attr('PART_NO', rec_.part_no, attr_);
		Client_Sys.Add_To_Attr('BUY_QTY_DUE', rec_.qty, attr_);
		Client_Sys.Add_To_Attr('DESIRED_QTY', rec_.qty, attr_);
		Client_Sys.Add_To_Attr('REVISED_QTY_DUE', rec_.qty, attr_);
		Client_Sys.Add_To_Attr('COST', rec_.unit_cost, attr_);
		Client_Sys.Add_To_Attr('PLANNED_DELIVERY_DATE', sysdate+7, attr_);
		-- ... There may be other fields you may wish to populate...

		-- Example of how to update an already-established attribute
		if (rec_.unit_cost = 0) then
			Client_Sys.Set_Item_Value('COST', '0.01', attr_);
		end if;
			Customer_Order_line_API.New__(info_, objid_, objversion_, attr_, 'DO');
			when other then
			info_ := sqlerrm;
			dbms_output.put_line('Cust Order ' || rec_.order_no || ' error: ' || info_);

   end loop;
