MRP Evaluation
Objective: Provide troubleshooting guideline for MRP evaluation guideline. This is an
exception process for troubleshooting purposes only.Material Planner own the
coordination with stakeholders e.g. buyer.
Material Planner will initiate the
troubleshooting upon escalation from buyer and validate the dependent demand
calculation. Upon verification on dependent demand, Material Planner will coordinate
with buyer to validate the procurement proposals and DOI calculation
Step 1 Identifying demand to validate
 Go to MD04
 Enter a UPI e.g. 2000-030-938. (Need to enter the independent demand UPI and it
will show all the piecepart attached to it)
 Hilite a Planned Order and click order report




It will shows the pieceparts dependent requirement for that UPI specific Planned
Order




Identify one piecepart e.g. 736229-004
Material Planner role is to validate if the MRP is calculating correct dependent
requirement for the chosen piecepart 736229-004

Step 2 Data Collection
 Go to CS03- View Material BOM
o Enter UPI - 2000-030-938
o Enter Plant – MYA8
o Enter BOM Usage – 1 (represent production BOM)
o Identify the attach rate e.g. 736229-004
o Go to General tab . The attach rate is under quantity column
 Go to MM03
o Enter UPI - 2000-030-938
o MRP1 – Get the assy scrap percentage e.g. 0%
o MRP2 – Get the in house production tpt e.g. 3 days
Step 3 – Dependent Demand Calculation
 Assuming the identified Planned Order is 50000 on 4/10/2010
 The dependent requirement formula is 50000 x 12 (attach rate) * [1 + 0% scrap
percentage] = 600000
 The requirement date will be 4/07/2010 (incorporating 3 in house tpt)
Step 4 – Procurement proposal + DOI Calculation
 Contact buyer for validation



If there’s issue, escalate to KTBR
