Utilizing UDA Members (Level 0/Parent Members) in Data Export via Data Integration Filter or Groovy

With Data Export in Data Management (Data Integration in Planning): We are experiencing difficulties in applying a filter condition for data export using UDA. The requirement involves exporting data for entities tagged with the UDA "ENG," which is applied at both Level 0 and Parent levels. We have attempted to use Data Integration with file export in DE, employing various filters to retrieve UDA data. However, each filter attempt results in an inability to construct the correct MDX query for UDA members. The filters tried include:

@Descendants("Global_Segment") and @UDA(“Entity”,”ENG”)

@list(@Descendants("Global_Segment") and @UDA(“Entity”,”ENG”))
