Simple finance Migration issue - Line item migration is not necessary in client 100. no data available

Hi Experts,

I am currently doing Simple finance migration project and the following activity.

1. Migrate accounting documents to Universal Journal Entry Structure

And getting below message :- "Line item Migration is not necessary in client 100.no data available"

Though I have 1 document in BKPF and 2 line items in BSEG. 2 line items from table FAGLFLEXA got deleted which is fine as SAP is not going to keep this table.

any solution to this pls.

Thanks in advance,

Arabinda
