Hi All, We are experiencing module problems during XQUERY Mapi execution with Mtest which we do not know how to solve. The problem is the Mserver does not know any command from the pftijah module which is already loaded en executing commands. Executing the same query through the mil interface of Mtest works correct. Execution through the MapiClient also works correct but execution through the Mapi interface with Mtest fails. DETAIL: Our XQUERY query containing pftijah functions is translated by 'milprint_summer'to a MIL script containing a call to run_tijah_query() which is in module(pftijah). This script is executed and the run_tijah_query() function is executed. This function in its turn generates a new MIL script where the first line is 'module(pftijah);'. When we execute this script this script does not kown any command from module(pftijah). It does however know functions from module(pathfinder). And this all happens in the Mtest/Mapi setting. In all other settings it works OK but here it fails! Anybody any ideas?? JanF
