How to read Inactive data for type 3 entity in sap mdg supplier

Hello Experts,

I am having one requirement to read inactive data in MDG-S i.e. country key, now as per BP data model  Country key is maintained as type 3 entity named as "AD_CNTRY" and for type 3 we dont have generated structures,  but in generated structures we have one structure of type 4 named as "AD_NAME_P" which is having one  country field named as REFNAMEP.

Now, my concern is till now I am reading the data through read_char_value method by passing the entity type as an input and reading all inactive data but how can I read the country key in this scenario.

Any useful help will be rewarded.

Regards

Ashu
