How to save the current settings of a transaction for reuse during the current session

Include the module SVSMOD into the transaction and integrate a call to SVSMOD.SvsSsnSave passing a list of fieldnames to be saved into an exit routine (see LnkLeaveAction). To restored upon restart implement in the init a call to SVSMOD.SvsSsnLoad.

Sample taken from TRNREL

sub SaveSettings
#! Procedure to save the current settings per session
$Fld = "\\TRNCORCO\\OWNREF" + CR + "\\TRNCORCO\\RELFLG" + CR + "\\TRNCORCO\\INIDATFRO" + CR 
$Fld = $Fld + "\\TRNCORCO\\INIDATTIL" + CR + "\\TRNCORCO\\INIFRM" + CR + "\\TRNCORCO\\INIUSR" + CR 
$Fld = $Fld + TRNCORCO\USFMOD.GetFltSvsFlds
SVSMOD.SvsSsnSave( $Fld, "M" )
DBCommit

How to make sure a rule is called when leaving a transaction?

See LnkLeaveAction

What is the meaning of LnkLeaveAction?

A rule having a name starting with LnkLeaveAction will automatically be called upon leaving the transaction. This rule will be called with two arguments, see internal documentation in SYSMOD, holding the type of exit and optionally the name of the target transaction.

A sample in LOGMOD is LnkLeaveActionLOGMOD where LOGMOD registers its close functions.

When running a LERGEN report, and openning the CSV in Excel special characters (i.e. ü, é, etc) are not formatting correctly in DNG101. Is this a Windows problem, a setting in DNG, or something else?

Use the copy to PC function to access the output and use a texteditor to determine whether the CSV was generated correctly. When using CSV the settings panel in the used report generator holds some additional configuration options which are important. Depending on the used Excel either ; or , should be used as separator and the setting of the Checkbox for output only data without sum's should be taken into consideration as sometimes Excel is intended to provide the calculations. Another important fact is UTF-8 as beeing used as the standard character set of DOKA-NG. It might be necessary to set the variable CSVENC to a encoding required by Excel (or the application reading the CSV). We know about Excel versions where the encoding “UTF-8+BOM” is needed as the file needs to be written with a BOM and UTF-8 as encoding.

If the last date has to be excluded, the following change is to be made:
