Summary :
Users encountering startup issues with the IGS multiplexer (igsmux_mt) when running SAP Kernel 7.20 or 7.20_EXT (non-unicode) with corresponding IGS, might face a failure due to the absence of the IGS multiplexer during initial load. This results in a subsequent error manifesting in dev_rd, indicating 'program IGS.BD1 not registered' when attempting RFC connections. The problem stems from missing SAP NW RFC library files essential for IGS multiplexer operation. To resolve, download "SAP NW RFC SDK 7.20" from the SAP service marketplace and follow instructions in SAP Note 1740754 for installation details. This is an interim solution until a permanent patch is issued.
