Rename Fields not working properly with mapping load
I am currently facing an issue with using Rename fields using mapping load in qlik sense. The code goes as follows, it is pretty clear:
[Map_Fields]: Mapping LOAD Field1, Field2
FROM [lib://abc.xlsx] (ooxml, embedded labels, table is Fields);
Rename fields using Map_Fields;
The issue is that the code is not working properly for some changes, for example when changing field name "Value" to "#Value", so adding special character #. Has any of you experienced this behavior (maybe you can list some other cases?) and eventually knows how to solve it?
The trouble also arises when using qualify - is there any way how to handle this smoothly and not completely manually? For example I have a field Customer, which then changes to Table1.Customer and suddenly my visualizations are ruined.
