根据分类属性内部名称+分类属性值查询物料信息的OData REST APIs、REST APIs有哪

Hi @QQ_13728929 

Thank you for your question! 

I’d like to recommend to bring more details and context to your initial inquiry. For example:

• Have you confirmed that the classification attributes you're trying to filter by are exposed in the OData metadata ($metadata) for the entity you're querying?
• Are you querying PTC.ProdMgmt.Part or a different entity set, and does that entity support classification attributes directly?

Please add screenshot(s) to better understand what you are trying to do in your process.
