SAP Note 27635 - Endless loop during generation of sets

Symptom:

When you generate a set, runtime error STACK_VALUE_TOO_LARGE occurs in FORM pool SAPLGSGE, Include LGSGEF20, FORM routine UPDATE_HIGHER_OBJECTS. This runtime error can also originate from routines READ-T800S or MODIFY-T800S in FORM pool SAPFGSB3 (Include FGSB0E01).

Cause and prerequisites

An incorrectly created usage list for a set leads to a recursive call of UPDATE_HIGHER_OBJECTS in an endless loop.

Solution
Please make the following correction in LGSGEF20 (insert the statements indicated with '<-- insert --'). As of Release 3.0B, another solution will be available in the standard system.
