Delete data from data store having some conditions to column similar to where clause in RDBMS

You will need to first fetch the primary key values from that table using queryEntity, and then delete the rows based on that key.

could u pls elaborate ?

Hi Deepak, I am trying it with save into but still the same issue,

a!cardLayout(
  contents: a!gridField(
    label: "Suites",
    labelPosition: "ABOVE",
    data: 'recordType!{0ab1955b-75e1-4395-87a8-d16e55c29b74}BTUA_AllSuites_RecordType',
    columns: {
      a!gridColumn(
        label: "Suite Name",
        sortField: 'recordType!{0ab1955b-75e1-4395-87a8-d16e55c29b74}BTUA_AllSuites_RecordType.fields.{7b3f7cbc-6a7e-4604-9b65-b1073301ce9e}suitename',
        value: a!linkField(
          links: {
            a!dynamicLink(
              label: fv!row['recordType!{0ab1955b-75e1-4395-87a8-d16e55c29b74}BTUA_AllSuites_RecordType.fields.{7b3f7cbc-6a7e-4604-9b65-b1073301ce9e}suitename'],
              saveInto: {
                a!deleteFromDataStoreEntities(
                  dataToDelete: {
                    a!entityDataIdentifiers(
                      entity: cons!BTUA_v2_Script_tbl_constant,
                      identifiers: {"6722c859-76b4-4aa8-ac82-3b3f93f903ba"}
                    )
                  }

                ),
                a!save(ri!isSuiteSelected,true()),
                a!save(ri!isScriptSelected, false())
               
                
              }
            )
          }
          
        )
      )
    },
    validations: {},
    refreshAfter: "RECORD_ACTION",
    showSearchBox: true,
    showRefreshButton: false,
    recordActions: {
      a!recordActionItem(
        action: 'recordType!{0ab1955b-75e1-4395-87a8-d16e55c29b74}BTUA_AllSuites_RecordType.actions.{a25985f0-edf5-48c3-9a5c-af500c96668e}newBTUA_AllSuites_RecordType'

Could you pls tell me what's the exact issue ?

Hi, could you please show me the record image?

I have used the data store entity instead of record

6722c859-76b4-4aa8-ac82-3b3f93f903ba is this the primary key value?

OK. And what is your goal?

yes,

6722c859-76b4-4aa8-ac82-3b3f93f903ba is the primary key 

 My goal is that, if someone clicks on a record name, then an expression rule should get executed which will truncate the table, here in the above scenario, I am trying with only 1 row for which the primary key is : 6722c859-76b4-4aa8-ac82-3b3f93f903ba

Is the entity which you are taking is correct?

The trick with Appian is, that action does NOT happen within expressions typically. Records are your business data objects, and related actions implement certain activities. Use Interfaces for display purposes and expressions logic.

This will require a fundamentally different solution approach than you might be used to.

I am doing a POC for an application with Appian Stefan. 

I found that I was missing onSuccess and onFailure attribute. It was so simple. 

By the way thanks guyz for your precious time and efforts.
