I'll explain this with one example. lets take inspection type 01. It is used for inspecting the incoming goods. An organisation may purchase different kind of materials like ROH, FERT or Spare parts.
Now when the requirement is like,
- Any ROH or FERT materials is purchased, Quality inspection is required with inspection results.
- When Spare parts are required, No result recording is required but only Usage decision.
In this case, 01 can be used for both cases but you need to maintain Insp with Task list/specification for first case whereas you don't do it for second case.
To avoid this job, you can configure Z01 inspection type. In default settings (in configuration) for Z01, you do set nothing among them.
This way, you would eliminate the scope of error of maintaining the relative indicator in material master. Instead you would only assign either 01 or Z01 following the material class.
This is the path to create an inspection type
QCCO> Quality inspection> Insp lot creation> Maintain inspection type.
Once created, you need to assign it to inspection lot origin by this path
QCCO> Quality inspection> Insp lot creation> Maintain inspection type> Maintain inspection lot origin & assign insp type.
Another thing you need to take care of is Variance while using multiple inspection type of a single lot origin.
Above is one example. There could be several others.
