How To Fix UCT8204 - Mapping rule for &1: Offset and length invalid

SAP Error Message - Details

• Message type: E = Error

• Message class: UCT8 - Message class for UCT8(mapping)

• Message number: 204

• Message text: Mapping rule for &1: Offset and length invalid

What causes this issue?

The mapping rule for target field &V1& contains a move with a concatenat
ion rule. However, the offset and the length for the concatenation
component &V2& are invalid (for example, because the offset exceeds the
boundary of the actual data, or because the length equals zero). The
mapping rule for concatenation component &V2& is presumably defined
incorrectly.

System Response

The system will not execute the mapping rule for target field &V1&.

How to fix this error?

Examine the mapping rule for target field &V1& and change the offset and
length for concatenation component &V2&. Execute the method again.
