By default documents (DOC items) have a field "Document Number".
The number in this field is used to create then name of the SIGN items.
If the document number is empty, the SIGN item will just inherit the name of the DOC item.
If there is something in the field, it will use it as a prefix for the generated SIGN, with the possibility to use the following macros.
|Macro||when creating SIGNed the document title will be replaced by|
|_id_||the id of the document, e.g. DOC-13|
|_serial_||replaces the document's number by the number with up to 3 leading 0s, e.g. the serial of DOC-13 -> will be 013|
|_serial1_ _serial2_, _serial3_, _serial4_||padding with 1, 2, 3 (same a _serial_) , 4 leading zeros|
|_project_||id of project|
|_title_||title of document (allows to move the DOC title into the middle of the generated SIGN name)|
|_YYYY_||year (of day of SIGN creation), e.g. 2017|
|_YY_||year after 2000, e.g. 17|
|_MM_||month, e.g. 05|
|_DD_||day, e.g. 03|
|_YYYYMMDD_||year, month and day, e.g. 20170214|
