Logic in case of Service PO

Question

Hello Team,
We have a service PO with account assignment category as K, Item category D, Material  - blank and only short text, PO document type is normal.
At item level we have two tabs service and limits. Under service tab we enter service number and under limits tab we enter expected value as 1000 ( this field is ESUH - SUMLIMIT.
Now we want to have logic in one of our report to fetch the value for SUMLIMIT from table ESUH. I got the logic to fetch the value. In table ESUH we have PACKNO as key field. We have PACKNO field in table EKPO too which can be read for PO number and item number.
I would like to know how the field PACKNO in table EKPO is getting updated and it's linkage with table ESUH> I tried to check from my side but not found the logic for the same yet.
Regards,
Deepak Gupta

ESLB Service Type Header of Standard Service Catalog
ESLH Service Package Header Data
ESLP Service Item
ESLL Lines of Service Package
i thing this only link between  purchase table like Po table  and service PO table
so we can link service po logic for service Po
