You can use Scripted rule and read response xml or as a string. below is the sample script to update it as a string.

int numberOfDays = sv.Request.numberOfDays;
string installStartDateTime = "30122023 12:00";
string installEndDateTime = "30122023 16:00";
string availableDateObject = "<ent:installStartDateTime>" + installStartDateTime + "</ent:installStartDateTime><ent:installEndDateTime>" + installEndDateTime + "</ent:installEndDateTime>";
string output = "";

for(int i =0;i<numberOfDays;i++){
output += availableDateObject;
}
sv.Response.availableDatesList = output;

Hi Syed, 

Thank you for your response. We have tried to implement the same and received below error.

Error - 'AvailablSeDate', rule 'Scripted Rule 1', operation 'request': Error [42:70] Cannot implicitly convert type 'string' to 'HP.SV.CSharp.AvailableDatesListType' (CS0029).

Could you please help us on it.

Share your script rule and the full sample response object. I will check it.

Hi Syed, Could you please share any FTP to share the details required.
