(SCR created on 3/3/2014) Manual input of unavailable maintenance and supply days. Have system auto calculate unavailable days based off of Work Order State Codes. Have system auto document these days by using State Code.? Have sub Work Order State Cd (i.e. AAWP - Approved Awaiting Part) trigger unavailable supply days and track the length of time until the State Cd changes back to the Work Order Sate Code of AIPR - Approved - In Progress . These days will be auto calculated and kept in the background until the parent Work Order close out. At this time days awaiting supply and days awaiting maintenance will be auto calculated by system and added to appropriate fields. See Link for similar USMC issue.
