Third Party Subcontracting for VC material with Statistical GR and 543 Sales stock issue

[Rasi0516]

Hello Experts, 
The Third party Subcontracting for VC material with GR into sales order stock ( 101 "E") and Component issue  with bot (543 "o" ) works. However when Statistical GR is activated with 101 to consumption, the consumption indicator "V" from PO is passed and only 543 "o" only works. The  component also is VC MTO material with inherited characteristics and Internally Manufactured against Sales order Stock. While doing GR 101 to consumption, 543 "E" has error still after maintaining V_156SC_VC " Check table T156SY: entry 543 X X E _ _ V does not exist.  The Account grouping entries cant be changed.  Is there a setup issue or its not supported.?

Additional note:

Also stumbled upon a OSS note161729 that has program ZMBXKOKO

to update XKOKO in T156 as 161729 - M7226 with KZVBR= V 
However the program didnt update XKOKO for 543
