====== SetDocumentSubType ======

Changes the subtype of the source document in the database. This function should therefore not be called several times in a loop.
Prerequisites are:
  * the specified subtype must exist in the same repository in which the current type of the document is defined and 
  * the subtype searched for must be defined with the same entity type.

The subtype is then set on the document and the subtype is written to the frame variable 'eBiss.DocumentVars.DocumentSubType'.

==== Syntax: ====

<code>SetDocumentSubType (<sub type>)</code>


==== Beispiel: ====

<code>SetDocumentSubType("MySubType"))</code>
