"When an PM order for the component is issued for a particular PM plan at a particular reading, the measuremnt document is created for this component measuring point during TECO of order. now this measuring point reading is diffrent than the main engine."
I understood the issue.
I can only say that, when you have a Measurement Transfer Arrangement, you can not have individual recording on these Component Measuring points. Everything should be through the Engine only.
(I remember, in the past I did restrict users from reading directly from the component measuring points)
