Disable Values for Collective agreements without loosing historical data

Summary:

Content (required):

Hi team,

We need to disable some old values for ORA_HRX_IT_LEVEL and ORA_HRX_IT_QUALIFICATION without loosing historical data.

We have done correctly the configuration in collective agreements task and we can see paired values qualification and level.

But, if you disable the lookup, values can still be selected in contract, instead if you delete association in collective agreement task, you loose all the historical data.

So I would like to understand how to proceed.

Thanks,

GF
