Answer for ORACLE LEASE MANAGEMENT TABLES.

Hi Mahesh,
High level, following are some of the main transaction tables:
1. Contract header : OKC_K_HEADERS_ALL_B, OKL_K_HEADERS
2. Contract party roles : OKC_K_PARTY_ROLES_B
3. Terms and Conditions : OKC_RULE_GROUPS_B, OKC_RULES_B
4. Contract Lines (Assets, Fees, Services etc.) : OKC_K_LINES_B, OKL_K_LINES
5. Streams : OKL_STREAMS, OKL_STRM_ELEMENTS
After contract activation, asset depreciation data is stored in Oracle Assets(FA) tables, Item instance data is stored in Installed Base(CSI) tables. Billing/invoicing gets interfaced to Receivables(AR) tables, whereas funding data resides in Payables(AP) tables.
