For those of you on classic HFM and upgrading from any version before 188.8.131.52, there is a small line of code that is needed in order for your .app file to work properly.
In version 184.108.40.206, the CUSTOM_ORDER property needs to be included in the header of the file. This property tells HFM which order the dimensions should be displayed – such as in a POV.
It’s a fairly simple line to add:
Remember it should be what the name of your dimension is; so if you dimension is named Product (instead of Custom1) use that instead. Also: the alias of any dimension should be less than 20 characters – or you will run into .app file load issues.
