Hi Raajakumar,
You can hide partner section in item details of Invoice.
Implement badi WD_BADI_DOMODIFYVIEW.
Develop logic in method IF_WD_BADI_DOMODIFYVIEW~WDDOMODIFYVIEW.
You can get view name as import parameter and set visible property of view /SAPSRM/WDC_DODC_PARTNER to 01.
Let me know if more information required.
Regards,
Vishal
