I was using Microsoft Dynamics AX excel add-in to import master data in Dynamics AX 2012 and the Publish All button was disabled after getting my excel sheet ready with data.
To publish the data using excel add-in, close the FIELD CHOSER window once you have selected all the fields you want to push to AX and then you will see Publish button enabled.
