Hi,
Please note that 'VENDOR_UPDATE' is an update function module. Update function modules are used to update corresponding database tables from the similarly structured ( work area or internal table ).
Ideally, it should have only update/insert/modify and delete statements. All the other validations w.r.t the data should be done before calling any update FM. This is because, we want update to happen quickly without wasting much logic on other section of the code in FM).
So, basically before calling this FM - you need to fill all the mandatory import and tables parameter and then call the FM.
Please find the usage of FM 'VENDOR_UPDATE' in Class VMD_EI_API->VENDOR_UPDATE .
call function 'VENDOR_UPDATE' in update task

i_lfa1 = cs_vendor-lfa1-new_data ( means fill LFA1 structure -> Vendor general data )

i_lfm1 = cs_vendor-lfm1-new_data ( means fill LFM1 structure -> Vendor purchasing data)
i_ylfa1 = cs_vendor-lfa1-old_data ( will contain the old values of LFA1, if data changed )
i_ylfb1 = cs_vendor-lfb1-old_data ( will contain the old values of LFB1, if data changed )
i_ylfm1 = cs_vendor-lfm1-old_data ( will contain the old values of LFM1, if data changed )
