Value in cusotm subtotal field is not updating in LIS (S) table

Hello Experts,

All the existing subtotal values (6 provided by SAP) we have used based on the pricing procedure's requirement and we have created a new Z subtotal field

(ZZKZWI11) in pricing also done the respective structure enhancements.  It is working fine and the values flowing into VBAP and VBRP tables under the Z subtotal field for all the transactions.

I have included the new subtotal field in LIS table (S503 copy of S003).  But the values are not getting updated in LIS table (S503).  I have executed the statistical update of order and invoice with OLI7 and OLI9 transactions respectively.  All the data is updating in S503 table except in the new subtotal field.

Please let me know how to flow the data into this new subtotal filed???

Thanks,

Sreehari.
