Hi Gaurav,
Sampling Procedure: A sampling procedure defines the rules that specify how the system calculates the sample size and it contains information about the valuation of an inspection characteristic during results recording (attributive, variable, manual, etc.).
Use: Sampling procedures are usually used at characteristic level of a task list or material specification. You can however determine the sample size, without reference to task lists. To do this, you define a sampling procedure in the settings at plant level or for the inspection type in the material master.
Structure: The rules for determining the sample are stored in the sampling type. The sampling type and valuation mode are combined for the inspection characteristics. This combination forms the structure of the sampling procedure.
Sampling Type: The sampling type defines how a sample is calculated (fixed sample, 100% inspection, use sampling scheme, percentage sample). Together with the valuation mode, the sampling type defines the parameters for sample determination.
Using the sampling type, the system proposes a list of rules for sample determination. If only one rule is suitable, it is automatically selected.
Valuation Mode: The valuation mode (for example, attributive inspection on the basis of nonconforming units, variable inspection according to s-method [one limit], no valuation) defines the rules for accepting or rejecting a characteristic or sample. The sampling type and the valuation mode specify which parameters the system uses to determine a sample size.
Inspection Points: If you want to use inspection points in the sampling procedure, you need to set an indicator for the corresponding application area. This indicator specifies how many inspection points are to be created for each inspection lot.
Usage Indicator: To prevent the sampling procedure from being referenced in a task list, you set the indicator No use in insp. plan.
The system automatically sets the indicator Use in insp. plan, if the sampling procedure is referenced in a task list.
Control Chart Type: If you want to use quality control charts in a sampling procedure, you must enter a quality control chart type.
The control chart type specifies:
The characteristics for which the control chart is suited
The control variables a chart contains
How the control limits are calculated
Special Indicator: If you do not want individual characteristics in an inspection plan to be dynamically modified, you can assign a sampling procedure, in which the indicator No stage change is set. In this case, the system determines the inspection severity for calculating the sample size for these characteristics from the sampling procedure.
Multiple Samples: You can create sampling procedures to plan:
Single samples and to record inspection results for a characteristic
Independent multiple samples and to record inspection results from different samples for a characteristic
Dependent multiple samples and to record inspection results from different samples for a characteristic
Sampling scheme: A collection of one or more sampling plans. A sampling plan applies to the sample size based on a specific inspection lot quantity and defines the criteria for determining whether and how a sample is accepted or rejected. In the R/3 System, the structure of the sampling plans complies with international standards (for example ISO 2859 and ISO 3951). However, you can also add sampling schemes for different sampling procedures.
Use :You use a sampling scheme if you want to:
1. Determine the sample sizes on the basis of the inspection lot quantity, inspection severity, or combination of inspection severity and AQL (actual quality level)
2. Store how a decision is made to accept or reject a characteristic
3. Determine the number of physical samples, based on the lot size, or the number of containers in an inspection lot in sample management.
Hoep it is useful to you.
