dynamic access by components

Hi Experts,

I have a scenario like this, I have a component module with a component list in a row as A(parent), (A1, A2, A3 are children) & B(Parent), (B1, B2, B3 are the children). I too have 2nd module with data like this, Area & Components are in a row time and line items are in a column and the line items are PY year(formula), Adjustment(input) & CY(formula)...

I have given the synchronize selection between the 1st module & 2nd module to the components, eg: if I can select component A in my 1st module I can see only A component and its associates(A1, A2, A3) in my 2nd module successfully.

Now I would like to give access to users who belong to the respective components can only do read or write the adjustments(line item) in the second module based on the component selection in my 1st module and all components A, B, C so on... can be visible to all but the users who have access to the components can access the module based on their accessibility(read or write).

eg: 1. If a user has access to component A with read access that the user can see only the component A and its associates and do not do any input or edit to the 2nd module especially do not input any value to the line item(adjustment).

2. If the same user have the access to component B with write access that the user can see only component B and its associates and can input or edit to the 2nd module.

Kindly help me with the solution.

Thanks in advance..!
