We had some old applications developed in PowerBuilder 10.5, me migrate them to Powerbuilder 2019 R2 and R3 version, now we are having issues running some store procedures in our informix DB  (9.40) under linux server

we are receiving this error at runtime:   Select Error:  SQL Error -674: Routine (routine_name) can not be resolved

do anyone had this issue before or may know what is causing it?
