XIF or BDoc Trigger even with errors in Business Document

Hello Experts,

I am stuck in an issue regarding BDoc trigger. My query is as per my understanding, if a business document like Sales order or Opportunity is in error but is saved, there is no BDoc triggered. Please correct if I am wrong.

My actual Requirement is to trigger BDoc and thus XIF IDOC if Opporutnity is saved even with error.

Do we have a method for this apporach.

Please assist.

Thx,

Ravi
