miro-substitution.pngHi Gurus,

I have maintained Section Code in SAP and create one Substitution (T. Code:- GGB1).

Automatic Section code update at the time of MIRO, but section code not update MIRO time. I have post entry FB60, FB65, FB70 and FB75, system automatic update section code, but MIRO time not update.
