How to avoid Automatic retrial of posted messages in B1if

Hi Experts,

            We are posting our data into SAP B1 through B1if HTTP (XML Content) call.

            In B1if, there occurs an scenario where the posted XML Contents were re-tried and our system shows duplicate entries were queued. We are not sure why the posted contents were tried again automatically and this occurs on 18 30 to 19 00 HRS IST.

            We have set the Default Error Handling in Cfg Errror Handling as “Remove from Queue and continue with next message”.

            Is there any settings to avoid automatic retry method.

Regards,
