How To Fix MC205 - Matchcode table has & bytes (maximum & bytes).

SAP Error Message - Details

• Message type: E = Error

• Message class: MC - Aggregate: views, matchcodes, lock objects

• Message number: 205

• Message text: Matchcode table has & bytes (maximum & bytes).

What causes this issue?

A pooled table definition is generated in the ABAP/4 Dictionary for
each physical matchcode ID (update types A, S or P) during generation.
This pooled table is stored in the pool of the corresponding matchcode
object.
All the fields of the matchcode ID could belong to the key. The maximum
key length of the pooled table, however, is limited to 110 bytes.
In order to ensure uniqueness within a matchcode ID, however, at least
all the key fields of the matchcode ID (i.e. all the fields which are
key fields of one of the tables of the matchcode ID) must lie within the
first 110 bytes. This is not the case here.

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

System Response

How to fix this error?

Either you must remove fields from the matchcode ID or you must change
the domains corresponding to the fields, so that the upper limit of 110
bytes in the key of the matchcode ID is not exceeded.
