Missing postings on Cost Elements in CO, only on GL accounts in FI

Hello,

There have been posted several FI entries on FI-accounts and Cost Elements were not created with the validity of the postings entries. So the status is that FI does not match with CO. Is there any T-Code or program to identify the missing CO entries and catch them up so that FI is matched with CO again. Cost Elements has been already created with the corresponding validity.

Thanks for any suggestions

Regards

Szymon
