Need to update print status for AR Credit memo

Hi Team,

We have 1000+ AR Credit memo for which we need to update Print status 'Y', but with existing REST API we are not able to update the same error: "'404 not found' is received, we raised SR as well and they mentioned that- there is no REST API to update Credit memos, REST API will only work for transaction class 'INV' they asked us to raise community question for the same.

Regards,
