Hi Friends, I worked with 8.2 not with 9.2. Please help me in this prob. I created one script and recorded some think and save as Test 1 then I opened process--open the object repository manager. Switch to file->save->give some name->save as Objectrepo1.tsr file. (This is the global repository file.) Then I went to object repository->tools-> associate repository ->click + icon ->open the previously saved Objectrepo1.tsr file. This is the global repository Now I created one more script and save as Test 2. In this script I am calling script with the Help of "Call of existing action" and I executed but QTP is not able to execute B’cos it is QTP is not able to read the Object Repository of Test 1. Please let me know why? Once I made Script 1 as a shared Obj. Repository so it would not give any Problem. Right?
