New business functionality in EHP7 LOG_SD_PRICE_LIST_2, gave report V_NLN

Dear Sirs,

I have activated a business functionality in EHP7 and it has given me a price list v_nln, an enhanced version of v/ld.

The report v_nln holds data such as customer, material, subtotal 1,2,3,4,5, tax, net value, etc. The subtotal 1 column shows negative value and all other columns except customer and material shows 0. Request you all to help me understand this report. Also the message screen shows a list of multiple errors and warnings. Is there a need for any configuration to rectify the errors?

Screenshot of the errors and report attached herewith.

Thank you in advance.

Regards Amit S.
