SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_DMC_MC_PE -

• Message number: 011

• Message text: Data access for table &1 is required for this field mapping

What causes this issue?

You have used field of table &V1& in field mapping, although table &V2&
is assigned as (one of the) sender parameter(-s) to the transfer step
parameter &V3& in the Structure Mapping. There is no 1:1 relation
between table &V2& and table &V1& due to one of the following reasons:
Table &V1& has the same or lower source table hierarchy level than table
&V2&
Table &V1& belongs to another source table hierarchy branch than table
&V2&.
In both cases several &V1& entries could correspond to the same &V2&
entry.
This field mapping is not valid without further information. You need to
specify exactly &V1& which entry has to be used as a value source for
your mapping.

System Response

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

How to fix this error?

Go to assign structure mapping screen of the transfer step parameter
&V3& and provide required data access for table &V1&
