Dear Sreekanth,
While running the MRP system will check the material master data first i.e. Procurement type, MRP Type and lot size, Quota usage and MRP Group. here especially MRP Group is used for capturing the PR Document type
if the procurement type is F/F30 /F40 then system will check the info record for this material combination who is vendor (if one or multiple)
then system will check the Source list (Here source list should be valid as per the info record and will maintain the MRP Relevant ) here system will confirm that which vendor combination it has to generate the proposals
lly if you maintain the Quota usage in the material master and Lot size then it will check the quota percentage for each vendor by considering the source list MRP Relevant vendors combination

Venkatesh..
