unable to add/save rapair line item in the workshop repair order through zprogram

Hi all,

I created a zprogram(module pool), through this program am adding 4 line items to the workshop repair order(CRM).

among  4 line items am unable to add/save one line item(which is repair line item). while try to save this item am getting "document_not_saved"

exception. this scenario working fine in DEV but in QA am unable to add that perticular item..

while debugging i understand that in DEV, when item is adding to order without calling any "actions". but in QA while adding its calling "actions" which i

didnt call in the Zprogram. i checked the actions in both sys all are same in both sys.  why its calling action while saving in QA?

please help on this...

thanks in advance.

vinnu.
