Oracle NCA Script error only on 2nd iteration

Hi All,

I am working on Retek Merchandising System scripting.

The script works fine for the first iteration perfectly fine, and at a particular step in the second iteration returns the ifError(100);

Note that the script has about 8 action sections with the following flow:

(VUSER_Init > Launch) - Init Section

(NavigateDeals -> DealMenu ->DealHeader ->DealComponents ->DealLocationThresholds -> SubmitDeal) - Action Section

(VUSER_End) - End Section

Steps at which it is failing is

nca_set_window("Add Deal Item/Location         (dealmain2)");
 nca_button_press("B_ITLC_ADD_PB_OK_0");
 lr_think_time(5);
 nca_set_window("Deal Maintenance                (dealmain2)");
 nca_button_press("B_MAIN_ACTION_PB_SAVE_0");
 nca_tab_select_item("C_ITEMLOC_THRESH", "Thresholds");

and sometimes at this step:

lr_start_transaction("SaveLocThreshold_Deal");

nca_button_press("B_MAIN_ACTION_PB_SAVE_0");

lr_end_transaction("SaveLocThreshold_Deal", LR_AUTO);

Funny enough, if i move the signout and signin into the action (ie. logout and close application as part of the action block), the script works fine.

Any pointers as to what may be wrong?

Regards,

AJ
