More details on TAT
For the computation of TAT (days) for the part, the system takes into consideration:
Goods receipts against General, Express, Exchange, PBH and PBH Exchange purchase orders other than AOG priority. TAT (Days) = PO Authorization Date - Receipt Date.
Release slips other than AOG priority. TAT (Days) = RS Authorization Date - Receipt Date
Repair receipts other than AOG priority. TAT (Days) = Issue Confirmation date (latest if there are multiple issues) - RR Received Date
If the ordered/requested/issued part is received on the same day, TAT (Days) will be 1.
