Every superiors:

        hello, now I have a question,please lost serveral minutes ,thanks very much.

     Q:  I publish a map layer by arcMap, this layer's data construct by two database's tables join in. A table is graphic table (picture aaa), B table is attribute table,the two   tables join by mme_fid,(A and B both have mme_fid).but the mme_fid not in published feature layer (the layer only can see the key field objectId ，not see the mme_fid (picture bbb)). when I create  a graphic  to graphic table A ,the mme_fid not saved. I don't know why?

I don't think you can edit a Joined table. You can join and view a Map Service, but a feature layer won't display a joined table. You will likely have to relate the tables instead so that you can edit them.
