Thanks for the reply.
I tried with reference in said two options but failed.
1. with same pattern in transaction references {xxx/YYYY} -> 004/2022
2. with blank reference column

01. I have installed and activated the extension "Import Transactions"
02. Then I downloaded and adapted the csv template to meet the GL code requerements ( Please see the attachment 01_deposit_en_GB.csv)
03. After that I did the import for deposits but ended with preview page without uopdating anything ( I untick the check box "Trial-run before importing. Do NOT process into database." also)

Please see the total process I followed in this video. https://drive.google.com/file/d/1TBYEIskSx3yumNalHOTltLNMUr51_jMx/view?usp=share_link
