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

Hello Experts,

All the existing subtotal vlues (provided by SAP) we have consumed based on the pricing procedure's requriement and we have created a new Z subtotal field (like ZZKZWI11) in pricing, it is working fine and the values are getting updated in VBAP and VBRP tables under the Z subtotal field for all the transactions.

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

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

Thanks,

Sreehari.
