Dear Raju,
Could you please confirm why you need derive business transaction?
Please note, it used when you want to derive the value based on position(TAX).
Say for example 1% of your share amount is charged as Brokerage or tax, in that case we create the DBT(Derive business transaction) and assign the same to BP for particular type.
example: 01A , Please make the customization in below path
In securities: IMG Path- Treasury and Risk Management-Transaction Manager-Securities-Transaction Management-Flow Types (Transaction)-Derived Flows
Here we make all customization for DBT
Here define derive flow type for example i have define for tax
And assign the same to product type 01A in standing instruction of your BP.
Hope this help.
Regards,
Jain
