Can someone please explain me on difference between following type of blocks?
a) Purchasing block
b) Posting block
c) Payment block
d) Block for quality reasons
a) Purchasing block: For blocking vendor at central level (purchasing block + Posting block) use T-code XK05
For blocking vendor at Purchase Level use MK05
b) Posting block: Go to MM02 >Purchasing View>Set the Indicator in the field of Plant-sp.matl status>as 01,it will block all the procurement at Plant level, or remove the authorization for movements in this plant, or use MMRV & remove the tick of Previous period posting for blocking posting in previous period.
c) Payment block:[Payment Block|http://help.sap.com/saphelp_47x200/helpdata/en/82/c2394ae8b211d1a57b0000e839d005/frameset.htm]
d) Block for quality reasons: There is a Quality Block (Block.reason: quality) check Box active in the MIRO,until we have cleared the Stock from quality inspection.
So we have to write in the Exit below
if this indicator SPGRC is "X" Configure an error message that material is in Quality inspection.
