PO-i-E  shows only the line items rec'd in.   It doesn't reflect tax.    This PO-I-E figure is the one that goes to the job costing module.  
 
Sales tax is at 10% on some items,  (non mfg & non raw mat).    This 10% not reflecting on job costing can be misleading.
 
How can I make sales tax reflect on the job costing.
We do not use  PO-invoices,  we use only AP-B vouchers.
 
Thanks
