How To Fix CNV_PE437 - RFC destination maintained on PCL and posting engine level

CNV_PE437 - Overview

• Message type: E = Error

• Message class: CNV_PE - General messages for posting engine

• Message number: 437

• Message text: RFC destination maintained on PCL and posting engine level

What causes this issue?

The &V3& RFC destination for posting engine project &V1&, area &V2& is
either taken from the PCL package or directly from the posting engine
area.
This is defined in table CNV_PE_PCL_DEST. Either the field PCL_PACKID is
filled (then the PCL package is taken as source) or the field RFC_DEST
is filled (the used RFC destination is taken right from this field).
The program found that both PCL package and RFC destination are filled.
This is inconsistent.
