Generation canceled: No field with this name

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

What causes this issue?

You are working with at least one subordinate source structure. However,
the source fields of the dependent structures you have entered are not
compatible with the other definitions within your LSMW object.

System Response

How to fix this error?

Correct your source field definitions in the step 'Maintain Source
Fields'. In the case of dependent structures, the key is given the same
name across all fields, meaning that in the subordinate structure, at
least one source field must have the name of a field of the
superordinate structure. During the import, this field is then used as a
key for the relationship between the two dependent structures. This
method ensures that the hierarchical source structure you defined can be
read correctly by the LSMW.
If you do not require a relational key relationship such as this, delete
the dependencies of the structures in the step 'Maintain Source
Structures'. In the case of flat structures, no fields of the same name
are required.
