plant based invoice split not required

Hello team,

I am creating an invoice against sales contract which contains two line item with different plant. But invoices are getting split while running VF01 and split analysis shows that different plant code is forcing system to split the invoice. I want to raise a single invoice with two line item with different plant. Please suggest how to achieve this.

I am using the standard routine "001" which splits the invoice only if distribution channel and division is different.

Immediate response will be highly appreciated.

Thanks,

TRV
