SAP Note 17636 - Syntax error in MKGALT8T

Symptom:

Controlling transactions abend with a syntax error in Include MKGALT8T.

Cause and prerequisites

There are operating concerns for which no active version of Table CE7xxxx (xxxx - operating concern) exists in the Data Dictionary. ABAP Include MKGALT8T is consequently generated incorrectly.

Solution
Check whether Tables CE7xxxx exist and are active in the Data Dictionary for the entries in Table T811T. If the tables are not active, proceed as follows:
if you use the operating concern, generate it again. Use transaction KE02 in Release 2.2 and
transaction KEA0 in Release 3.0
or
if you do not use it, delete the entries CE7xxxx from Table T811T.
Then execute Transaction KEUG once more for an operating concern to regenerate the Include.
To eliminate the problem quickly, you can use the second option first, and generate the operating concerns later.
