Inspection plan - Describes the steps to carry out inspection of a material. It tells in which order the inspection has to be carried out and which characteristics are to be inspected.
Inspection plan can be assigned to one or more materials.
One or more operations can be assigned to an inspection plan and similarly one or more MIC/ sampling procedure can be assigned to an operation
Tcode to create an inspection plan is QP01.
Business scenario : Create an inspection plan for a plastic bottle manufacturing plant
The quality team wants to implement a structured in-process inspection during bottle manufacturing. The inspection must include:
1. Operation 10 : Visual and Basic checks ( MIC - Surface defects and Color consistency (Attributive))2. Operation 20 : Dimensional Measurement ( MIC - Height, wall thickness, neck diameter(conditional), Weight per bottle(calculated)(Quantitative))
3. Operation 30: Drop test ( MIC - Drop test result, Crack Observation (Qualitative))
Steps:
- Create MIC's for all 3 operations. Here the MIC'S that is to be created are Surface defects, Color consistency, Height, wall thickness, neck diameter, Weight per bottle, Drop test result, Crack Observation
- Go to tcode QS21 and create MIC
- Next go to QP01 and MIC to inspection plans as per the business scenario given
- Inspection plan will have 2 sections Header and Operations. Header will contain information that is applicable for the whole plan and the inspection plan is uniquely identified by task list or operations
- Operations describes individual inspection setup in an inspection plan. One or more MIC's are assigned to an operation
- Calculated characteristics - This can be activated in the control indicators. The formula to calculate characteristics can be maintained in the task list of the inspection plan and based on this the result will be calculated. To make this work, all the MIC'S that are maintained in the formula must be assigned to a single operation
- Conditional characteristics - The inspection of conditional characteristics depends on the result of the previous characteristics i.e. after acceptance and after rejection
- Long term inspection - If the characteristics requires inspection even after performing UD, then this can be activated in control indicators
- PRT - Production Resource Tools- A PRT is any tool, instrument, or resource that is used temporarily during a manufacturing or quality inspection process. In Quality Management, PRTs typically refer to Measuring instruments (e.g., calipers, micrometers) Testing equipment (e.g., tensile testers, weighing scales) Calibration devices used during inspections
- Material specifications - A Material Specification is a master data record in QM that stores inspection characteristics and specification limits for a specific material, especially for incoming inspections (QM in procurement). Tcode QS61.
| Feature | Material Specification | Inspection Plan (Task List) |
|---|---|---|
| Tied To | Material + Inspection Type. | Material + Plant |
| Contains Ops? | ❌ No operations | ✅ Yes, has steps/operations |
| Use Case | Incoming inspections (raw materials) | In-process or final inspections |
| Setup | QS61 / QS62 / QS63 | QP01 / QP02 / QP03 |
| Control Level | Simple & centralized | Detailed & process-specific |
| Master Data Type | Specification-based | Operation-based |
