Thank you in advance for the help. 预先感谢您的帮助。
To me it appears that the Customer_ID is formatted as Text in the one table, but not in the other. 在我看来,在一个表中,Customer_ID的格式设置为文本,而在另一表中则没有。 If so, is there a way to have the field formatted the same way in both sources? 如果是这样,是否可以在两个源中以相同的方式格式化字段?
If not, you may be able to get around it by using the FORMAT function in a calculated column (in the table that has numbers formatted as text). 如果不是这样,则可以通过使用计算列(在具有数字格式为文本格式的表中)中的FORMAT函数来解决此问题。 You could then use that calculated column for your join/relationship. 然后,您可以使用该计算出的列作为联接/关系。
Some info on the Format function: http://social.technet.microsoft.com/wiki/contents/articles/685.power-bi-dax-text-functions.aspx 有关“格式”功能的一些信息: http : //social.technet.microsoft.com/wiki/contents/articles/685.power-bi-dax-text-functions.aspx
Edit: Also, I just realized that this error may be caused if you have a text value in a column that is numeric. 编辑:另外,我只是意识到,如果在数字列中有文本值,则可能会导致此错误。 You may need to review your data to see if that scenario exists. 您可能需要查看数据以查看是否存在该情况。
