We have a problem while calling a Function Module in SAP by using a SAP RFC connector (call). The error is:
“”A failure happened during the execution of the provided operation! The failure was: {net.liftweb.json.JsonAST$JInt cannot be cast to net.liftweb.json.JsonAST$JString}” ”
I am not sure that it is about the data type or not, the Test Result in Call returns this error.
this seems to be a validation problem with the data type, make sure the data types match and test again. Also make sure that you have created a Structure for your valueset and have assigned the right datatypes for your values.
