Import from excel_Journal Entry_Cash Flow Line Item ID

[DaoTran1988]

Dear Expert,
I have a template to import from Excel below:

When I import many journal entries the system will message: Enter valid code for Row Number 7
I try to manually a journal entry and have value in the field Primary Form Item or importing a single Journal Entry is okay.

But cannot import many journal entries.

Please help me to check it.

Thank you so much.
