How to change the status value?

Hi Experts

We landed in the starnge situation. We defined a multi task EE Monitor activity to change the status attribute to past due when particular internal event code is overdue. We forgot to assign the correct EE monitor Activity to EE Profile and the report /SAPTRX/EE_MONITOR converted the internal event code to overdue but did not change the status to past due for lakhs of records.

Now we assigned the correct EE Monitor activity to the EE profile. How do we change the status to past due for already processed records? Is there any standard program available for this purpose or shall we need to write any custom program for it?

Your quick response is much appreciated.

Thanks

Ravi
