Definition: A physical or logical place at which a status is described.
- Temperature inside a reactor
- Speed of revolution of a wind wheel
The status is described using measurement readings. Measuring points are stored in the SAP System as master data.
How to create Measuring Point in SAP PM:
Step 1: Run T code IK01 or follow this path on easy access screen Logistics -> Plant Maintenance -> Management of Technical Objects -> Environment -> Measuring Points -> IK01 (Create)
Step 2: Initial screen will appear.
Step 3: Select IEQ as measuring point object, if you are creating measuring point with reference to Equipment. You can select IFL as measuring point object, if you want to create measuring point with reference to Functional Location.
Step 4: Enter the Equipment number or functional location, with reference to which you want to create measuring point.
Step 5: Select measuring point category. Generally we select M category. There are configuration settings related to measuring point category in SPRO. We will discuss them in detail in coming posts.
Step 6: Enter Measuring Position. Here you can enter the measuring position.
For example: In Equipment like Transformer, Silica Gel is a measuring position. Where electrical department monitors its condition on daily basis and record its condition in system.
Step 7: Enter the description. Here you can enter the short description of measuring point (max 40 characters). You can also maintain the long description.
Step 8: Enter characteristic. Characteristic brings the properties of the object which is under monitoring.
For example: If we are monitoring Temperature of a reactor, then we will have to create a characteristic in CT04 t code, with unit of measurement Degree Celsius, no. of decimal places and total no. of digits.
Step 9: Once characteristic is entered, automatically unit of measurement and no. of decimal places will copied to measuring point data.
Step 10: Value Code Sufficient check box. If there is no measurement reading entry is required, only value code is sufficient.
For example: In a machine, we want to check whether level of lubricant oil is OK or NOT OK. In such a case you do not required any unit of measurement and reading to enter. In such cases we SET this check box.
Step 11: Enter code group. Code group is configured in QS41 T code. Code Group contains the code and code text.
For example: Code Group can be Lubricant Level. Code can be 0001 and 0002 or could be an alpha numeric code. Code Text can be OK, NOT OK etc.
Step 12: Enter Authorization Group. Authorization Group is used to restrict certain user to see and process measuring point.
For example: Many times a particular department does not want other department to see and process their data, like mechanical department does not want electrical department to see their measuring point readings.
Step 13: Enter Target value. Target value is the desired or the ideal value of measuring point reading. It is the optimum value of measuring point.
Step 14: Click on the Additional Data button. A pop up box will appear.
Step 15: Enter the upper range limit and lower range limit of measuring reading.
For example: If we are recording the temperature of a reactor and we want to define a range of this temperature like upper limit = 250 C and lower limit = 150 C. Now if temperature goes beyond this range, then system will throw an error or warning message, depending upon the setting in SPRO.
Step 16: Click on SAVE button and system will generate a new measuring point with a system generated number.
