we are integrated with one application like "xyz". In servicenow we have 3 different tables like table1,table2 and table3.
3 tables sending data independently to xyz application through 3 different integrations.
in the table1 one field is reference to table2 and in table2 one field is reference to table3.
for sending data to xyz application through integration need to check other table data already available in that xyz application or not.
Before sending table2 data to xyz application first we need to check table 1 data already available in that xyz application. How can i achieve this.
