Firm zone/tradeoff zone

Question

Hi all,
Presently I am working in a SAPscript.I have copied the standard SAP script medruck.There is a data element ESTAT
for the field indicator: firm zone/tradeoff zone. Based on the value of this indicator I have to print some schedule line item in the script. This field is present in the table EKPB, but in the client server there is no data in this table. Can any one suggest me that except EKPB which table may I use to retrieve the value of indicator: firm zone/tradeoff zone??
Thanks in advance

Hi,
Rolling delivery schedules issued under scheduling agreements are divided into different time zones indicating the degree to which lines of the schedule are binding.
Firm zone (zone 1) (go-ahead for production).
The schedule lines within this zone count as firm and thus as fully binding. If you cancel a schedule line that falls within the firm zone, the vendor is entitled to charge you with both production costs and the costs of procuring input materials incurred by him as a result of the cancellation.
Trade-off zone (zone 2) (go-ahead for procurement of input materials)
This is the "semi-firm" zone, giving the vendor the go-ahead to procure necessary input materials for the manufacture of the item ordered. If you cancel a schedule line within this semi-firm zone, the vendor is only entitled to charge you the material costs. Schedule lines falling within this time zone are thus less binding that those falling within the firm zone.
