From the information I have gathered so far regarding legacy data transfer, the following steps need to be done:
1) Create the transaction
2) Settle the transaction ( else change the processing category)
3) post the transactions using TBB1_LC
However, in case of valuation specific information I have the following concerns:
1) Is there any specific Tcode which will provide me this valuation related information which needs to be maintained in tcode: TPM63C or TPM61A for OTC , securities and Derivatives as our legacy data is maintained on SAP itself.
2) In case of securities , is the creation of securities position indicator Tcode:TPM61 necessary to be created?
Kindly provide your guidance on the above.
Thanks & Regards,
