String array rule

Hi Alex

A two-step process will give you what you need:

Step 1: use fn!index() to extract the actual values

Step 2: use fn!joinarray() to splice the values together with the separator of your choice

a!localVariables(
  local!myArray: {
    {idSecurityMaster: 20202},
    {idSecurityMaster: 20203}
  },
  fn!joinarray(
    fn!index(local!myArray,"idSecurityMaster"),
    ","
  )
)

I've NOT included any handling for circumstances where the values maybe null, or the array returned doesn't contain any 'idSecurityMaster' dictionary items...

Thank you very much for your time Stewart, it works perfectly

You're welcome. Half the battle in Appian is trying to find the right functions, and the other half is breaking down your problem into a set of smaller problems.

I'm sorry Stewart
Another question, at the end the first rule that obtains the values ​​I left it as in the first img

Because the results of the rule I need to put using the in operator in another rule, but it shows me the following error.

Thank you

When you run 'SAN_ST_GetListAssetsByPortfolio' what type of data does that return? The error message is saying you can't use the 'IN' operator (which will always be a list) to compare the field 'securityMaster' to the values returned by this rule.

Yes, it is clear that it is due to the data type. In the first image you can see on the right the result of the first rule which is List of text string, which I think is the one needed by the IN operator

If the data types are different you can coerce (cast) one or both of them to be the same type before applying the operator.

Thanks, i used the split function, it seems to work fine. Once again thanks for your time
