Why ‘nca_list_select_index_item’ throws "UnknownFunc_Action" error message in vugen ?

Hello All,

We have created a Oracle Web (NCA) script for EBS application. We are getting "UnknownFunc_Action_<line number>" error at "nca_list_select_index_item" function after executing all transactions while validating in VUGen.  Please suggest.

lr_start_transaction("S02_Prd_Release_T01_Assignment");
    nca_list_select_index_item("RULES_RTT_ASSIGNMENT_0",1); // This function is causing an error during vugen validation.
lr_end_transaction("S02_Prd_Release_T01_Assignment",LR_AUTO);
lr_start_transaction("S02_Prd_Release_T02_Rule");
    nca_list_select_item("RULES_RTT_RULE_0", "Pick_Rule");
lr_end_transaction("S02_Prd_Release_T02_Rule",LR_AUTO);

lr_start_transaction("S02_Prd_Release_T03_Rule_Release");    
    nca_button_press("RULES_RTT_PR_RELEASE_0");
lr_end_transaction("S02_Prd_Release_T03_Rule_Release",LR_AUTO);    
    nca_console_get_text(RuleReleaseMessage);

Error: Vuser started transaction "UnknownFunc_Action_119", but did not reach a corresponding end transaction statement. The transaction ended automatically with status 'fail'.

 

Thanks, VRCK
