Sana Indexing Strategy
When using the SANA indexing strategy, it copies product and customer changes from the standard SAP table CDHDR to the custom Sana table /SANAECOM/CDHDR. When updating the product and customer indexes, Sana checks product and customer changes not in the standard SAP table CDHDR but in the custom Sana table.
Sana provides the Webshop Indexing program in SAP which you can access by calling the transaction code /n/sanaecom/index.
There you can define how many days to keep material and customer changes for Sana indexing in the custom Sana table and automatically delete the history.
You can create a background job to run this Sana program automatically according to the schedule.
