Our client have just upgraded from 4.7 to ECC 6.0 and when processing securities, according to them they didn't need to go through TBB1 before doing TPM10 back in 4.7. In summary this is their process:
4.7 (OLD) --> FWZZ (Create contract master data) --> TS01 (create transaction) --> TS04 (settle transaction) --> TPM10 (post transaction) --> TPM18 (fix amortization).
When they tried doing the above steps in ECC 6.0, they can not proceed with TPM10 because the system can not find the specific transactions. I've researched about it and I've read in SAP HELP that you would have to do TBB1 first before doing TPM10. Is this a documented/recognized change for the Treasury module when upgrading from 4.7 to ECC 6.0? Is there any SAP note or document that could enumerate normal changes for the Treasury module and could explain the reason for such change? Please assist us on this as I am not so familiar with the Treasury processes. Thank you!
