SAP Error Message - Details

• Message type: E = Error

• Message class: AD_SUBCON - Messages for Subcontracting

• Message number: 119

• Message text: In recursive repair, both materials (item and comp.) must be serialized

What causes this issue?

You are trying to carry out a recursive repair in Subcontracting for MRO
Processes. This means that you send a part to the subcontractor and
receive the same physical part back after repair. You use subcontracting
type <LS>Refurbishment with Unchanged Material Number </>(1) or
<LS>Refurbishment with Changed Material Number</> (2). However, only one
of the issuing or receiving materials is serialized, meaning the serial
number profile is assigned in the material master.

System Response

The system stops processing.

How to fix this error?

Check the serial number profiles in the material master record, if
required.
Ensure that both the issuing and receiving materials are either:
Serialized
Non-serialized

Procedure for System Administrators

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