i am not sure if i had understood your question correctly.
Why don't use use statement to count the no of rows in internal table after split statement and all the field have been appended in internal table.
Something like:
describe itab lines v_lines.
If v_lines gt 10.
Message 'Blah Blah' type 'E'.
Endif.
It would be of better understanding if you can post your code.
