Auto complete rule to default context value

Summary:

Hi Team,

We have a requirement, when creating a job requisition if the HM selects Business Justification as "Replacement" we need to enable a field(replacement for) which will have the LOV to be selected. For this we have created a context dff and added the same values as in the business justification field and when selected value is Replacement then Replacement For field will be shown else no.

This context value is created in details section of Job requisition, since we have created this HM has to select the Business Justification in two places "Basic Info" section and "Details" section, to avoid this we are thinking of creating a auto complete rule which will pick the value of Business Justification from Basic Info section and populate in Details section. Has anyone done something similar?
