/*
DISABLED THIS STEP (20190722.27) ON PURPOSE BECAUSE IT STARTED CAUSING FAILURES ON MSSQL FOR A FRESH DB.
I left it here for historical purposes.
The reason for the failure is as follows. The TARGET_CODE column was originally 'not nullable' when it was
first introduced. And in 7_2_0, it is being changed to a nullable column (see 20240327.1 in init720()).
Starting with 7_2_0, on a fresh db, we create the table with nullable TARGET_CODE (as it is made nullable now).
Since we run all migration steps on fresh db, this step will try to convert the column which is created as nullable
to not nullable (which will then need to be coverted back to nullable in 7_2_0 migration).
Changing a nullable column to not nullable is not allowed in
MSSQL if there is an index on the column, which is the case here, as there is IDX_CNCPT_MP_GRP_ELM_TGT_CD
on this column. Since init720() has the right migration
step, where the column is set to nullable and has the right type and length, this statement is also
not necessary anymore even for not fresh dbs.
