Hi Gurs,
Substitution is not working for T.code: MIGO, Plant and Exchange gain or loss cost element. Cost center (xxxx) should substitute.
I have defined prerequisite as below
SYST-TCODE = 'MIGO' AND BSEG-WERKS = '1100' AND
BSEG-KSTAR = '6300010'
Substitution defined for cost center(xxx).
GL : 6300010 will not pick for all GRN documents but it pick for few GRN. When ever through GRN pick GL 6300010 it should pick cost center.
Regards,
Sai.
