Field help (OFLCTL) 

Flow control. This parameter is linked to the parameter of the product record called "Output locking".
If it is active, when "issuing" a product whose output is locked, the system performs a control and refuses to issue the product.
If it is inactive, irrespective of the value of the "Output locking", the product output from stock can be completed.
Output controls are carried out during the following transactions:
- entry of the DO lines
- search for stock objects on output
- adjustment on deletion or quantity decrease
Transfer movements remain possible irrespective of the parameter value.
