Dear Experts
As part of SAP QM Implementation we are implementing control chart functionality to get graphical representation against measured values for pre-defined parameters. I am facing two issues mainly:
1. When I try to calculate control limits (clicking calculator button) getting message "Control limits for track 1 could not be calculated". MICs has the upper limit and lower limit maintained which I can see in QAMV table for the inspection lots.
2. In the attached control chart , I am getting Upper Limit, Lower Limit and the Valuated Result in graphical form, when I try to display the inspection date, for the characteristics against inspection lot, I get lost. System is showing some date 7/14/14 against all the characteristics which I am not sure how to achieve.
Settings I made:
Sampling type: Fixed sample
Valuation mode: SPC inspection
W/O inspection point
Sample size: 5
Chart type:115 Shewhart chart for X bar/USA
MIC Settings:
Quantitative / Lower / Upper Sp. Limit / Sampling Procedure / SPC Characteristics / Summerised Recording / Required Char.
Inspection plan setting is:
SPC criterion : 020 task list char/material
Base qty : 1KG
Control Chart Configurations:
1. Control Chart Type -115
a) Change Control Limit not checked
b) Characteristics Type- Fixed Scope, Record measured values
c) Reference Axis (x-axis) - Time of Creation ( Do I need to change here to "Object Number" or "Time Of Inspection" ?)
Any input will be highly appreciated.
Regards
