Issue regarding consecutive run for an Interface

Question

hi all,
i have an issue regarding an interface
if this Interface is a initial run for the file, you have to populate all the data of the people. That is , unlike other interfaces where we send only the latest record, in this interface we need to send all the records of the employees. in a employee has 10 records with different dates, we will pick up all the records greater than 1999 and pass it. whereas if there is a change in one field, then we will send all the record of that file. And If it is a consecutive run  then you have to populate changes only. the following algorithm can help you in this
if intial_run EQ 'X'
transfer IT_FINALDATA to XI.
else
Declare a 2 more internal tables similar to IT_FINALDATA...for our below example let us assume that
         DATA: IT_CLUSTERDATA type standard table of IT_FINALDATA.
         DATA: IT_COMPAREDATA type standard table of IT_FINALDATA.
use the following statement to retrieve the data from cluster and comparing it
        IMPORT IT_CLUSTERDATA TO IT_COMPAREDATA  FROM DATABASE indx(zn) ID 'IN_8085'.
        Compare IT_COMPAREDATA with IT_FINALDATA
If sy-subrc = 0.
Means there are no changes, and no output required
Else
Pass the data to XI interface,  And store the internal table in the same INDX table, using the following statement
EXPORT IT_FINALDATA to  IT_CLUSTERDATA FROM DATABASE indx(zn) ID 'IN_8077'.
Endif.
In this  can we deliver the changed data at every single consecutive run.
Please let me  know,
Thank Q

This is something where HR Interface Toolbox (PU12) can be very helpful, it will take care of changes from one run to another and you can configure it to send changes only in next run. But, you will need some ABAP in its user exits to restrict the data after 1999, and any other restrictions that you might want.
