Summary :
During the "System Analysis" phase in the process control tree, the "Generate Conversion Objects" (PC002_MT_RT_GEN) activity results in two types of errors due to issues in data dictionary differences and accessibility. Error DMCLG 457 highlights generation issues caused by discrepancies in the data dictionary between sender and receiver systems, specifically in non-SAP tables or customized SAP tables. Error DMCLG 248 indicates problems in accessing DDIC data due to non-existing tables at given RFC destinations. Solutions involve redefining conversion objects through "Define Mass Transfer ID" (PC002_MT_DEFINE) and using rework report CNV_MBT_TS_OBJECT_REWORK to manage obsolete or altered objects effectively.
