Steps to reproduce

• Create a new user macro and added 12 or more parameters:

  ## @param Dokumenttyp:title=Dokumenttyp|type=string
  ## @param DokumenttypPlural:title=DokumenttypPlural|type=string
  ## @param Auflistungsseite:title=Auflistungsseite|type=string
  ## @param Sortierung:title=Sortierung|type=string
  ## @param Sortierkriterium:title=Sortierkriterium|type=string
  ## @param Bsp:title=Bsp|type=string
  ## @param SeitenAnfang:title=SeitenAnfang|type=string
  ## @param Titel:title=Titel|type=string
  ## @param Kurztitel:title=Kurztitel|type=string
  ## @param TitelSpeicherformat:title=TitelSpeicherformat|type=string
  ## @param Inhalt:title=Inhalt|type=string
  ## @param ShowHistorie:title=ShowHistorie|type=string
  

• Save and will fail with:

It should be possible to have more than 12 parameters to a user macro as this doesn't affect other DB.

Possible Cause

We found out that the described error is the result of the column BANDANAVALUE in table BANDANA being too small (CLOB(100000)) in DB2. We have many large user macros so it is only possible to enter a few macros until the maximum column size is reached. In MySQL this column is of type mediumtext, which is larger.

Workaround

We worked around the error by manually enlarging the column via db2 command.
