Hello,

I have created a workspace to download attachments from Survey123 for ArcGIS which works perfectly, apart from one thing. Some of the attachments are stored in related tables and as a result don't pull have the sample ID field included and this is causing issues further down the workflow.

I need to create a workflow that compares the parent ID field against the whole globalID column. If it finds a match, then it copies the sample ID field to the appropriate line and replaces the NULL field.

Does anyone know how to do this?

Split off the records with a null value for SampleID (TestFilter) and then use a FeatureMerger or FeatureJoiner to join them back to the other records.

FME rocks! \m/
