Hello,
Below is one of the questions and an answer related to integrating data from ECC Z tables into IBP using HCI.
Is there an option to create custom(Z) tables inside IBP? If answer is NO, then where would HCI store this data that is extracted from ECC Z tables.
Q: Z tables - If the master data (Product & Customer) is stored in custom database tables in ECC, can HCI read these data?
A: Yes, HCI can read the from custom Z tables (via the ABAP layer, no database access needed).
