Were you able to determine the fix for this as I am experiencing the same issue. However, my issue might be related to mappings having asterisk as part of the source and destination maps.
Ok, we have it working now. Some things you should consider to make this work:
1. Your FDMEE target values in the Data Load Mapping should match exactly the member names (not the Aliases) in Essbase. Check your Category and Period mappings as well. (ex. If it's FY17 in the outline, you should have FY17 on your target year, even though 2017 is accepted as an alias.) 2. The FDMEE target values in the Data Load Mapping should also match the case of the member names i.e. if it's ACCOUNT1 on the Essbase outline, it should be ACCOUNT1 on your target 3. Values with * to * mappings will work granted that the source value satisfies the above conditions, since for this type of mapping the target is just getting the source values.
