Currency key is not assigned to ISO code

Hello all,

Hope you are all safe and healthy.

I have a question for the below program.

Program : RBDMIDOC

Variant : CREMAS

As far as I understand, it is capturing the vendor master changes and then we are moving the changes to another system.

Error : Currency key *** does not have an ISO code

I have checked all the vendors for currency changes but I dont find any currency changes. Is there any other changes affects the currency?

Appreciate your quick response.

Thanks
