Which event triggered on posting of returns

Hi gurus,

We are trying to post a return document and during posting and then prit it using FPCOPARA. Unfortunately during printing, an error comes like 0000 items selected. we are assuming the DFKKCOH table is not getting filled which results in an empty dfkk container.

We tried events to check which event is getting triggered while posting, but despite putting breakpoints we are unable to zero in n the particular event.

i have 2 questions.

1. has anyone faced the situation in FPCOPARA where due to unfilled DFKK* tables we are unable to print? if so, how do we fix it?

2. how to zero in on a particular event which is being triggered when the postings are made?

any help will be highly appreciated. thanks!!

regards,

suman
