Field help (TRSCOD4) 

This setup is used to define for this entry transaction a movement code used to specify rules for a specific type of movements.
These codes must be created in the miscellaneous table number 14.

The movement code is used to define specific stock issue rules for some transactions. For instance, a stock issue with status "Q" may be authorized for a dedicated transaction assigned to advanced users. 

SEEWARNINGThis is only possible for the product categories authorizing this type of issue rules and having such a movement code (seeProduct category").
