a!exportDataStoreEntityToExcel(

Can you give us an example of what filtering you've already tried, and what's happening wrong (i.e. breaking, or just not getting the expected results, etc)? 

Also: are you already familiar with writing query entity rules using a!queryEntity and, more importantly, a!queryFilter and a!queryLogicalExpression?  If not, I suggest you start there since generally the same logic is used in these, but in a way that's far easier to test.

Mike,

I've been using and writing query entity rules for a long time. The Additional Details section for the function in Documentation doesn't show anything about how to construct the query inside exportDataStoreEntityToExcel but infers that it is possible.

Just a working example would be nice.

The help text that pops up when you click inside the rule seems pretty sufficient - the "filters" parameter takes a list of a!queryFilter or a single a!queryLogicalExpression (which itself can nest indefinitely further).

I was actually able to quickly write this example interface just now, and have even generated an example file and downloaded it to check:

a!sectionLayout(
  contents: {
    a!buttonArrayLayout(
      align: "START",
      buttons: {
        a!buttonWidget(
          label: "Click",
          saveInto: {
            a!exportDataStoreEntityToExcel(
              entity: cons!PROJECT_DSE_CATEGORY_TYPES,
              saveInFolder: cons!GLBL_DOC_UPLOAD_TEMP_DIRECTORY,
              documentName: "Export DSE to Excel Example",
              filters: a!queryLogicalExpression(
                operator: "AND",
                filters: {
                  a!queryFilter(
                    field: "ActiveFlg",
                    operator: "=",
                    value: true()
                  )
                  /* add more filters here if/when needed */
                }
              )
            )
          }
        )
      }
    )
  }
)

Thanks, I was trying to put oo much into it.

*too much
