Is there any way of making an field readonly after getting the input from a zoom section ..I can't use the field sections as I don't have access to the script of the session ..Please guide I am totally stucked up ...

I cannot think of a solution that does not involve the session script. Assuming the profile means this is baan iv you can have access to the script. See ~vamsi thread in code and utilities to extend source code. We use qkey and there is an RMCis product, but ~vamsi's solution is free.

if the zoom session is customized session , u can export certain values like procesinfo$ or attr.input to parent and use the values to check whether input allowed (by writing condition expression like procesinfo$="" in input/ref for the field ) . This however u need to test comprehensively to c that it works in all situations .
