Master Inspection Characteristics

 What is Master Inspection Characteristics?

It specifies how and what kind of inspection has to be carried out and what needs to be inspected. Is it quantitative(measurable) or qualitative(descriptive) and how the results are carried out is it summarized results or  single result and is the characteristics optional or required etc.

It plays a crucial role while performing result recording

Tcode : QS21/QS23/QS24

Some of the important fields in MIC

1. Preset Indicator - Can be configured from the path SIMG-> Quality Management -> Quality Planning -> Basic Data -> Inspection Characteristic, Inspection Method -> Define Default Values for Control Indicators. This helps in presetting the control indicators beforehand
2. Quantitative characteristics - If the characteristics can be measurable then this is used. Ex: length
3. Qualitative characteristics - If the the characteristics are not measurable and if it is descriptive then this is used. Ex: Color
4. Status - If the MIC has to be in use then the status has to be released
5. Complete copy model - Upper limit, lower limit and target value are specified in MIC(If it is quantitative)
6. Incomplete copy model - Upper limit, lower limit and target value are not specified in MIC unlike Complete copy model, they are entered while performing result recording
7. Reference char -  If upper limit, lower limit and target value are altered for one task list, then there is no need to change them in all the task lists wherever this MIC is used.
8. Catalogs - Used specifically in qualitative char. They are predefined set of values used for inspection to record results
   
   
   

Control Indicators : 

Lower Specification Limit : Specifies the lowest tolerance limit that can be accepted

Upper Specification Limit : Specifies the highest tolerance limit that can be accepted

Target value : Specifies the value that can be accepted

Sampling procedure : Formula to calculate how much samples are to be taken for inspection

Summarized recording : Takes an average of all the recording and provides the summary of the outcome

Single results : It is required to enter individual results in the system

Required char : While performing result recording it is not allowed to skip any characteristics and results of all characteristics has to be entered. If this is configured then Auto UD will not work

Optional char : It allows users to skip all or some of the characteristics while performing RR

After acceptance : The next characteristic must be inspected only if the previous one is accepted (result = 'A')

After Rejection : The next characteristic must be inspected only if the previous one is rejected (result = 'R')

Scope not fixed : If this is selected, then the number of inspected units are not precalculated but the user can defines it while performing result recording

Fixed Scope : If this is selected, then the number of inspected units should correspond to the precalculated value

Smaller scope : If this is selected, then the number of inspected units can be smaller than the precalculated value

Larger scope : If this is selected, then the number of inspected units can be larger than the precalculated value

Long term Inspection : Result recording can be performed even after UD is performed for the lot
