SAP Note 18888 - Return from 'Change material type' function

Symptom:

Transaction: MMAM
Program: SAPMM03Z

1. If the 'Change material type' function is accessed from another application (for example, from the class search), the program does not return to the calling application after the material type has been successfully changed. This problem can occur up to and including
release 2.2C.

2. If the 'Change material type' function is called directly from the
material master menu, this menu returns after successful material type
change, but the initial screen of the 'Change material type' function
should return. This problem can occur after release 2.2D.

Cause and prerequisites

So far, the program did not support the call from other applications.

Solution
to 1. The error will be corrected in 2.2D.
to 2. The problem will be corrected in 2.2G and 3.0C.

An advance correction is possible at the end of the module AENDERUNG_DURCHF by changing the coding of the Include program MM03ZI00
as described below:

MODULE AENDERUNG_DURCHF.
