Hi Praveen,

then please follow steps :
1: OX18 : 1st delete the assignment your company code to plant
2: OMSY : update current years & months
3: OMY6 : position your company code and make sure fiscal year variant should be "K4"
4: goto OX18 n then assign again company code and plant
5: OMWD : click on position n give plant code then give value grp code 0001
6: OB65: give company code and then unchecked business area FS
and make sure material should have enough qty to do PGI
