Hello Dmitry,
I have gone through most of the processes successfully using the methods and techniques you suggested and all have worked except for one process.
It account creation in the account application using a custom version.
The account number is correct using the specified check sum method.
Below is the relevant error log
Current Request Name: CreateAccount
Current Params: {accountTitle1=SUZANNA, accountNumber=181019269517
, customerId=92695, mnemonic=SAA, accountRef=233234633656, currency=USD}
Nested Exception:-
org.t24.driver.T24Exception: T24 OFS Error: @ID:1:1=INVALID ID FOR COMPANY
Any help will be much appreciated.
Thanks
