Hello
A record of clearly identifiable inspection results that are assigned to an inspection operation.The inspection points are identified by the user by a combination of fields, whose meaning is defined based on their usage.
inspection points are used for result recording based on time, quatity and to identify any event,time , date, inspector name etc
for eg
Vessel/Date/Time
In the process industry, liquids are produced in vessels. This operation can take several days. A sample is taken on an hourly basis (a time-based inspection interval, interval = 1 hour). By maintaining inspection point in the routing or inspection plan we can go on recording results based on time for hourly basis. at the same time we can identify the vessel number, shift , time, inspector name. There are different inspection point available for usage.

You define inspection points in this step. This involves defining the following:
Identification of inspection points
Default values for valuating the inspection points
Function modules for generating the inspection points
To identify the inspection points, the inspection point data record can contain a date and time field. For each of these fields, there are two text and number fields of variable length that you can freely define. You use these fields when recording inspection results, to assign the inspection points to the units that have been inspected or to the partial quantities. You do this by selecting one of the flow variants stored at operation level.
The standard system, therefore, provides the following inspection point types
Freely defined inspection points to identify partial lots in production
You need this inspection point type, for example, if you create inspection lots for a production order and want to carry out several inspections for each operation during the production process.
Inspection points to identify samples
You need this inspection point type if you want to manage samples and record inspection results for physical samples
Inspection points to identify maintenance objects
You need this inspection point type if you want to carry out calibration inspections and record the results of test equipment inspections or inspections of functional locations.
Inspection points during the production process
The identifiers for the inspection points are defined in the task list header and are valid for all operations. If you do not define an inspection point identifier in the task list header, the system uses a general identifier, that is stored in the settings at plant level.
Inspection points form the basis for defining partial lots with their own usage decisions. When used with control charts, inspection points are suitable for statistical process control.
If you define the use of inspection points in the task list header, you must specify whether the inspection points are to be based on time, quantity, or to be freely defined at the operation level. For inspection points based on time or quantity, you must also specify an inspection interval in the operation. During the production process, you create a data record that contains inspection results for each inspection point.
You must assign a produced quantity to each inspection point. You can combine the partial quantities for inspection points into partial lots and the partial lots into batches.
quantity-based inspection interval and the management of batches or partial lots is not supported.
please revert back if you require more clarification
