Logistics Data Interpretation (LDI)

LOGISTICS DATA INTERPRETATION (LDI) - The LDI course provides an in-depth 

review of all information contained within a NSN and related data elements contained 

within a Total Item Record (TIR). The Federal Logistics Information System (FLIS) TIR 

is analyzed and interpreted using standard DLA products and services. 

Key Learning Objectives:

 Identify and interpret every data element found on a Total Item Record (TIR)

 Get to know DLA as a member of the DOD and how the agency can assist you in your mission

 Discover the processes and tools involved in the lifecycle of a National/NATO Stock Number (NSN) from requisition to 

disposition 

 Discover the various DLA tools available to identify items of supply, and replacement parts, check the status of an 

order, verify price and unit of issue, and more 

 Become an authorized user of an item for asset visibility and procurement purposes 

 Obtain and interpret drawings and other technical data for items of supply 

 Know the difference between a Design Control Activity (DCA), Manufacturer and Distributor of an item of supply 

 Discover the reasons why duplicate NSNs might exist 

 Identify obsolete parts and why they are still in the Federal Catalog System 

 Gain an understanding of the importance of accurate and descriptive technical data and how it impacts the 

characteristics of an item of supply 

Attendees will learn: 

 Asset visibility and procurement issues can be �ixed with proper data 

 The NSN TIR provides vital information like criticality status, DEMIL procedures, and hazardous material status 

 Replacement items of supply can be veri�ied by understanding how to interpret characteristics found on the TIR 

 The difference between a DCA/manufacturer and distributor of an item of supply is clearly marked on the TIR 

 Phrase data found on the TIR will clarify the unit of issue of an item of supply 

 Not all NSNs originate in the United States

 Only systems and applications authorized by DLA can be used for researching NSNs

 Obsolete parts are never deleted from the TIR

 NSNs with minimal to no characteristics might be due to the lack of technical data availability or provided at the time 

the NSN was built

Attendees will be equipped to answer common questions asked by customers, such as: 

 What goes to a depot for repair and which depot performs the maintenance? 

 Who is authorized to use the item?

 If I want to become a user on an item, who do I ask? 

 Who is authorized to submit/change any data element on an item? 

 How can you identify an active, U.S. or foreign, restricted or obsolete, CAGE code? 

 Where is service speci�ic information located and how do you interpret that line of data (COG code for Navy)?

 Who is my or the NSN’s Source of Supply? 

 How do I research an NSN based on characteristics only?
